p.m.
October 14, 1943.
26,000 ft over Germany.
60B7 bombers fell from the sky in 4 hours.
600 American died or captured in single afternoon.
Everyone said long range fighter escorts were impossible.
Army Air Force’s brass said physics prevented it.
Punderbolt maximum range 375 mi.
German border 400 miles into Reich.
Simple math, impossible.
They were wrong.
One plane could fly 1,200 miles, could reach Berlin, could fight 20 minutes, could fly home, and generals had this plane sitting on their airfields, called it useless, relegated it to reconnaissance, turned it into dive bomber.
Germans believed American fighters couldn’t reach central Germany.
Doctrine built on this assumption.
This blindness would destroy Luftwafa.
Before this plane, American bombers lost 60 aircraft per mission deep in Germany.
600 men per raid.
Unsustainable losses.
Daylight bombing campaign failing.
After this plane, Luftwaffa broken in 4 months.
German pilots dead over their own capital.
Air superiority achieved.
Strategic bombing succeeds.
War shortened by estimated 612 months.
How did rejected aircraft design with wrong engine become weapon that won air war? The answer lay in two mistakes that became one solution.
American airframe, British engine, paper fuel tanks made from cardboard.
Combination seemed ridiculous.
Liquid cooled engine in combat.
Flimsy external tanks.
Untested integration.
Germans expected fighters to turn back at border.
Standard pattern since 1939.
They had no idea 500 silver sharks were coming to Berlin.
But first, this miracle plane had to overcome problem.
Everyone who flew it said it was death trap.
October 1943.
Eighth Air Force bleeding to death over Germany.
Daylight precision bombing doctrine.
Fly high drop accurately destroy German industry.
Theory worked on paper.
Reality slaughter.
American strategy required hitting factories deep in Reich, ballbearing plants at aircraft factories at oil refineries at problem distance from English bases to these targets for 1600 m one way.
Round trip 80012000 miles.
B flying fortress could make the distance.
Fighters could not.
P47 Thunderbolt.
Excellent fighter.
Rugged, powerful, heavy.
Drank fuel like alcoholic drinks whiskey.
305 gallons.
Internal fuel.
Maximum combat radius 375 mi.
German border from England 400 m.
Math didn’t work.
Fighter escorts turned back at German border.
Waggled wings.
Dove for home.
Left bombers naked.
Luftwaf awaited.
German fighter controllers tracked American formations on radar, watched escorts peel away, gave order.
Die send die send.
The Indians have left.
The wagons are uncovered.
Then massacre.
August 17, 1943.
Raid, 60 bombers lost, 600 men.
October 14, 1943.
Second raid, 60 bombers lost, 600 men.
Two missions, 120 heavy bombers destroyed, 1,200 dead or captured.
Eighth Air Force had 1,000 operational bombers total, losing 120 in 2 weeks.
Unsustainable.
General did math.
At this rate, entire force wiped out in 10 weeks.
October 1943, daylight bombing suspended.
Americans admitted defeat.
Luftwafa had won.
Fighter escort problem.
Simple physics.
Aircraft range determined by fuel capacity divided by fuel consumption.
Combat adds complications.
High power settings.
Maneuvering.
Altitude changes.
Each burns more fuel.
Punderbolt 2,800 lb and Whitney R2800 radial engine.
Air cooled, bulletproof, rugged, but inefficient.
Consumed 100 gall per hour at cruise power.
150 gall per hour at combat power.
Internal fuel 305 g.
Theoretical endurance 3 hours at cruise.
Reality reserve needed for combat landing emergencies.
Practical combat radius 375 mi.
Fighters needed to reach 600 m to protect bombers over prime targets.
Army air force has tried solutions.
Attempt one, P38 Lightning twin engine fighter.
Longer range.
Result: good but insufficient.
Maximum radius 450 mi.
Still short.
Attempt.
Two.
External drop tanks for P47.
Metal tanks 75 gallons each.
Result: help, but not enough.
Added 100 m range.
Still left gap.
Attempt three.
Fly fighters faster.
Catch up to bombers deeper.
Result, burned more fuel arriving.
No net gain.
Attempt four.
Accept losses.
Build more bombers than Germans could shoot down.
Result: bomber production couldn’t keep pace with losses.
British tried same problem, different theater.
Daylight bomber offensive abandoned 1940 after unsustainable losses.
Americans stubbornly continued.
Believed precision bombing essential needed daylight for accuracy.
But physics remained physics.
Fuel didn’t magically multiply.
Engines didn’t become efficient through willpower.
October 1943.
Expert consensus.
Long range single engine fighter impossible.
Laws of physics prevented it.
Anyone claiming otherwise ignored.
August 1943, 3 months before Black Thursday.
Test results arrived from England.
British Royal Air Force tested modified aircraft.
American P-51 Mustang airframe.
British Rolls-Royce Merlin engine installed.
Test pilot report.
Aircraft achieved 441 at 25,000 ft.
Handles superbly at altitude.
Recommend immediate production.
Range calculations attached.
600 plus miles combat radius with external tanks.
US Army Air Force’s Material Command reviewed report.
Lieutenant Colonel Mark Bradley, Chief of Fighter Procurement, filed assessment.
P-51 aircraft unsuitable for escort role.
Liquid cooled engine vulnerable to ground fire.
Coolant system represents catastrophic singlepoint failure.
One bullet in radiator.
Engine seizes within 5 minutes.
Pilots require rugged aircraft.
Punderbolt air cooled radial survives significant battle damage.
P-51 liquid cooling unacceptable fragility.
Recommend continue P-51 production for ground attack role only.
Unsuitable for air superiority missions.
Assessment stamped approved.
General Henry Hap, commanding ETH Air Force received copy, made no objection.
P-51s continued shipping to England assigned to tactical reconnaissance squadrons.
Low-level photo missions, train strafing, bridge attacks, most dangerous missions, highest casualties, plane called pilot killer by men who flew it.
Meanwhile, B7s kept dying over Germany.
September 1943, seven heavy bombers lost permission average.
October 1943 12 heavy bombers lost permission average losses accelerating army head longrange fighter called it unsuitable used it to strafe locomotives while strategic bombing campaign collapsed bureaucratic inertia would kill thousands but three men refused to accept verdict test pilot who felt the balance engineer who ran the numbers commander who ignored regulations December 1942 two right field Dayton, Ohio.
That’s when Robert watched his brother die.
Captain James, B17 pilot.
Eighth bomb group flew mission to Leo, France.
November 9, 1942.
German fighters swarmed formation after P47s turned back.
190s attacking from headon.
20 cannon shells through cockpit.
James tried holding formation.
Tried keeping badly damaged bomber flying.
Left waist gunner already dead.
Right waist gunner wounded.
Top turret jammed.
190 made second pass.
Shells through right-wing fuel tank.
Fire erupted.
James gave bailout order.
Rang alarm bell.
Watched six crew exit through bomb bay.
Stata controls holding plane steady while men escaped.
Last man out.
Ball turret gunner.
Then James tried exiting through overhead hatch.
Plane exploded before he reached it.
Robert got telegram December 1st.
Brother missing in action.
Presumed dead.
Confirmation came December 8th.
French resistance found crash sight.
Found body still in pilot seat.
Harness unbuckled.
Two feet from escape hatch.
Two feet.
Robert test pilot at right field.
Flew every fighter army had.
He knew capabilities.
Knew limitations.
knew his brother died because P47s couldn’t fly far enough.
New bomber crews dying every week.
Same reason.
He read dismissive assessment of P-51 with Merlin engine read unsuitable for escort role.
He thought about James trying to reach overhead hatch about 2 ft.
That night, Robert couldn’t sleep.
Kept seeing cockpit fire.
Kept hearing alarm bell.
kept thinking about crews dying over Germany while perfect escort fighter sat on ground doing reconnaissance.
December 3, 1942 walked into commander’s office, said seven words that would change war.
Sir, I request permission to prove them wrong.
December 1942, Robert studied P-51 Mustang performance data.
Original design, North American Aviation, 1940.
Built for British purchasing commission.
Sleek airframe.
Laminer flow wing.
Aerodynamically perfect.
Problem.
Engine.
V710.
Good at low altitude.
Suffocated above 15,000 ft.
Lacked two-stage supercharger.
British rejected it for fighter roll.
Americans used it for ground attack.
Everyone agreed.
Beautiful airframe, wrong engine, useless for high altitude combat.
October 1942.
British engineers at Rolls-Royce had different idea.
They pulled P-51 into hangar at removed engine installed Rolls-Royce Merlin 61 two-stage supercharger designed for altitude.
Test flight November 1942.
Pilot climbed to 30,000 ft.
Engine didn’t choke.
Roared.
Speed at 25,000 ft.
441.
Faster than Spitfire.
Faster than 190.
faster than anything flying.
Data sent to right field buried in bureaucracy.
Found it ran calculations.
Merlin engine 30% more efficient than at altitude.
Specific fuel consumption 0.48 lb per horsepower hour versus 0.624.
P-51 airframe 30% less drag than P47.
Laminer flow wing reduced parasitic drag significantly.
Math was simple.
PB with Merlin, 180 gal internal fuel.
Add two 108 gallon drop tanks, 396 gall total.
Fuel consumption at cruise power, 60 gall per hour.
Endurance 6.6 hours at 300.
Cruise speed 1,980 mi.
Total range.
Reserve 30% for combat.
Landing errors 1,386 mi.
Practical range.
Combat radius 693 mi.
London to Berlin 600 m.
Math worked.
Stared at numbers.
Ran calculations again.
Same result.
He thought about material command assessment.
Unsuitable for escort role.
He thought about liquid cooled engine vulnerability argument.
Then he remembered Spitfire used liquid cooled Merlin.
British had no concerns.
Four years combat proven reliability.
Vulnerability argument myth.
Propaganda by P.
47 pilots who love their rugged radials.
Had data had proof.
Had solution to problem killing bomber crews weekly.
He needed demonstration.
Needed someone to see P-51 with Merlin in action.
needed believer, not bureaucrat.
He found one.
Major Thomas Hitchcock, former fighter pilot, currently heir in London.
Passionate advocate for bomber crews.
Wrote report, sent it to London, included all calculations, included British test data, included one sentence.
This plane can save lives we’re losing every week.
January 1943, Hitchcock flew modified P-51B at climbed to 30,000 ft, pushed throttle, felt acceleration, landed, made phone call to General Carl, eighth Air Force commander, said stop production of everything else.
Build this, build thousands.
But even with believer at top changing production line midwar six-month nightmare and bomber crews didn’t have 6 months they were dying now.
P-51B Mustang masterpiece of engineering compromise.
Airframe design laminer flow wing special shape maximum thickness at 50% cord instead of 30% like conventional wings.
Reduced drag by 30%.
Wing area 233 square ft.
Aspect ratio 5.8:1 optimal for high-speed efficiency.
Fuselage streamlined.
Minimal frontal area.
Radiator scoop underneath belly.
Designed to create thrust from cooling air.
Effect at high speeds.
Cooling air heated by radiator expanded provided small thrust boost.
Partially offset radiator drag.
Engine installation.
V1650 Merlin Americanbuilt version of British Rolls-Royce Merlin 61,490 horsepower at 3,000 RPM two-stage two-speed supercharger supercharger critical altitude 19,000 ft first stage 26,000 ft second stage maintained sea level horsepower up to critical altitudes engine that breath efficiently in thin air liquid cooling system.
9 gall ethylene glycol coolant circulated through engine block cylinder heads cooled in radiator underbelly.
Vulnerability concern overblown coolant system had redundancy self-sealing lines.
Armor plate around coolant tank British combat experience 1% engine failures from cooling system damage after four years combat.
P47 pilot spread myth.
Suspected jealousy.
Fuel system.
Internal tanks 180 gall 85 gall each wing 10 gall behind engine.
Fuselage tank 85 gall behind pilot.
Created center of gravity problem when full.
Made plane unstable.
Burned off first before combat.
External drop tanks.
Innovation that made long range possible.
First version metal tanks 75 gall each heavy expensive supply limited solution paper tanks British invention layers of craft paper pressed together with animal glue coated with rubber compound for fuel resistance.
Weight 20 lb empty versus 80 lb for metal tank.
Same 108 capacity.
Cost $2 each versus $90 for metal tank.
Structural integrity sufficient for single mission designed to be disposable.
American pilots called them suicide bags.
Ground crews called them brilliant.
Armament 6.50 caliber Browning M2 machine guns.
Three per wing, 400 rounds per gun, 2,400 rounds total.
Rate of fire, 800 rounds per minute per gun, 80 rounds per second combined.
Muzzle velocity 2,900 ft pers.
K14 gyroscopic gun site revolutionary.
Computed lead angle automatically.
Pilot dialed in target wingspan.
Gyroscope’s calculated deflection.
Floating reticle showed aim point.
Turned average pilot into ace.
Performance numbers told story.
Maximum speed 441 at 25,000 ft.
Climb rate 3,200 f feet per minute.
Service ceiling 41,900 ft.
Range with external tanks 1,300 plus miles.
Combat radius 65750 mi depending on mission profile.
For comparison, P 47D 433 2,800 ft per minute climb, 42,000 ft ceiling, 475 mi combat radius.
P-51 be matched or exceeded P47 in everything except one characteristic, ruggedness.
P47 could absorb tremendous damage.
Aircooled radial engine kept running with cylinders shot away.
P-51 couldn’t.
Liquid cooling.
If radiator punctured, engine failed within minutes.
Trade-off, ruggedness for range.
Bomber crews needed range more than ruggedness.
Dead pilots in indestructible fighters didn’t help bombers over Berlin.
Live pilots in fragile fighters escorting all the way saved lives.
March 1944.
Eighth Air Force had 200 P-51B Mustangs.
Pilots hated them.
Fighter groups equipped with P47 Thunderbolt since 1942.
Pilots loved Jug, trusted it, knew it came home with holes in fuselage, oil streaming, chunks missing.
Pilots walked away.
Now headquarters ordering switched to unfamiliar aircraft.
Pilots revolted.
56 Fighter Group England.
Thunderbolt outfit.
Legendary hub commanding.
Orders came down.
transitioned to P-51B.
Pilots threatened mutiny.
They walked around new Mustangs kicking radiator scoops pointed at liquid cooling lines.
Said one bullet, 5 minutes dead.
They didn’t want sports car.
They wanted tank.
March 3, 1944.
First conversion training flight.
Captain Don Gentile, fourth fighter group.
58 days earlier flew Spitfire now climbing into P-51B cockpit.
Gentile experience pilot.
Seven kills.
New fighters.
Sat in cockpit.
Felt cramped.
Canopy narrower than Thunderbolt.
Visibility worse than Spitfire.
Strapped in oxygen mask.
Radio check.
Ground crew walked around doing pre-flight.
Checked control surfaces.
Checked gear.
Checked radiator scoop.
Crew chief leaned in.
Sir, don’t get hit in the radiator.
Helpful advice.
Gentile started engine.
Merlin coughed.
Caught.
Settled into smooth wine.
Different sound than Thunderbolts.
Thunder.
Higher pitched.
Sewing machine versus jackhammer.
Taxi out.
Long nose blocked forward visibility.
Had the Eston to see ahead.
Annoying.
Takeoff.
Smooth.
Acceleration.
Impressive.
Lighter than Thunderbolt.
Climbed faster at 10,000 ft.
Gentile tried maneuvers.
Roll rate excellent.
Better than Spitfire.
Turn rate tight.
Surprisingly tight.
Climb phenomenal.
3,200 ft per minute like elevator.
At 25,000 ft.
Merlin still pulling strong.
No wheezing, no struggling, just power.
Gentile pushed throttle forward.
Acceleration continued.
Airsp speed indicator wound up 380 400 420 faster than he’d ever flown in combat.
He tried dive, nosed over.
Air speed built rapidly.
450, 480, 500.
No flutter, no vibration.
Solid.
At 500, he pulled up.
Geforces crushed him into seat.
Vision grade.
Plane didn’t complain.
Pulled through perfectly.
Gentile climbed back to altitude.
Tried scissors maneuver.
Tried barrel roll.
Tried everything he knew.
Plane responded instantly.
No lag, no mushiness, just pure connection between thought and action.
He understood this wasn’t Thunderbolt, wasn’t Spitfire.
This was something different.
This was scalpel.
Landed, taxied in, shut down.
Sat in cockpit 2 minutes before climbing out.
Crew chief asked, “Well, sir,” Gentile said.
Get me 500 of these.
Next two weeks, intensive training.
Pilots practiced formation flying.
Practiced fuel management.
Practiced drop tank procedures.
Critical procedure.
Drop tanks.
Tanks hung under wings on shackles.
Pilot pulled lever.
Clamps released.
Tanks fell away.
Problem.
If tanks didn’t release cleanly, hung up on wings.
Created massive drag.
Made plane.
Solution: practice.
50 practice drops per pilot before combat mission.
Also fuel management.
6 hours in cockpit.
Pilots needed discipline.
Lean mixture settings.
Cruise power only.
Save fuel for combat.
Burn external tanks first.
Switch to internal tanks before combat.
Drop empty externals before fighting.
Mess up sequence.
Die over Germany with empty tanks.
Also pissing.
6 hours flying.
Bladder doesn’t care about mission importance.
Solution.
Relief tube.
Rubber hose.
Funnel.
Drainage overboard.
Dignity zero.
Practicality essential.
March 4, 1944.
First operational mission.
Target Berlin.
Eighth Air Force launching 800 bombers, 500 fighters.
Biggest raid yet.
Deepest penetration.
Germans would throw everything at them.
P-51 pilots would find out if fragile sports car could survive real combat.
or if crew chiefs were right about one bullet 5 minutes dead March 4, 1944 a.m.
Airfield, England.
62P51B Mustangs from fourth fighter group started engines.
Pilots ran through checklist Magneto’s oil pressure hydraulics oxygen radios.
Each aircraft carried two 108 paper drop tanks hung under wings like gray sausages.
Pilots still skeptical.
Paper tanks looked ridiculous.
Craft paper and glue holding aviation fuel seemed insane.
Ground crews assured they work.

You go to Berlin, you fight, you come home.
Anyone lands short of base from fuel mismanagement.
Court marshall clear guidance.

Cross German border at Braymond.
Normally P47s turned back here.
Not today.
Mustangs continued straight.
Didn’t waver.
German radar operators tracked formation.
Confused.
Fighter escorts should turn back.
Doctrine stated escorts reached fuel limit at border.
Why were escorts still coming? Luftwafa fighter controllers issued standard orders.
Wait for escorts to withdraw, then attack bombers.
German pilots circled at 30,000 ft above clouds.
Waited.

Dog fight exploded across 20,000 ft of sky.
109’s 190s Mustangs turning, diving, climbing, scissors, barrel rolls.
German pilots confused.
These American fighters shouldn’t be here, shouldn’t have fuel, shouldn’t be matching German performance.
But Mustangs were matching everything.
Out turning 190s, outdiving 109’s out climbing everything.
Captain Don Gentile chased 109 down to 10,000 ft.

Final tally, five German fighters confirmed destroyed.
Three probables, zero P-51s lost.
All aircraft returned.
Mission success.
News spread through Eighth Air Force like wildfire.
Impossible mission succeeded.
Berlin reached.
Enemy defeated.
But German high command refused to believe reports.
Herman Goring declared American fighters reaching Berlin physically impossible.
Ordered pilots stop making false claims.
Reality was coming whether he accepted it or not.
March 8, 1944.
8th Air Force flew four more missions to Berlin.
Each mission P-51 Mustangs escorted all way.
Results.
March 4.
Five German fighters destroyed.
Zero Mustangs lost.
March 6, 11 German fighters destroyed, two Mustangs lost.
March 8, 23 German fighters destroyed, three Mustangs lost.
March 9, 19 German fighters destroyed, one Mustang lost.
Five missions, 58 Luftwaffa fighters confirmed, destroyed, six Mustangs lost.
Exchange ratio 9.6:1, unsustainable for Germany.
More importantly, bomber losses dropped dramatically.
Before Mustang escorts, 10 12% loss rate per mission, 60 bombers average.
With Mustang escorts, 2 3% loss rate, 15 bombers average, 75% reduction in bomber casualties.
Strategic bombing campaign saved.
Within two weeks, every fighter group in Eighth Air Force converting to P-51B P47 Thunderbolt groups resisted initially.
Commander ordered, “Convert or go home.” They converted.
April 1944, 400 P-51 Mustangs operational in England.
May 1944, 600 Mustangs.
Production ramping exponentially but effects spreading beyond England.
Luftwafa realizing American fighters everywhere.
No safe training space.
No sanctuary.
Terror spreading through German pilot ranks.
April 1944.
Mustang impact multiplying.
Not just bomber escort.
Entire air strategy changing.
General James issued new orders.
Destroy enemy air force.
Old orders stay with bombers.
Protect formations.
New orders.
Pursue enemy fighters.
Hunt them down.
Kill them.
Mustangs unleashed.
Fighter pilots given free reign.
Chase German fighters to their bases.
Strafe airfields.
Destroy planes on ground.
Results catastrophic for Luftwafa.
April 1944, Luftwafa lost 489 fighters, 20% of entire fighter force.
Single month.
May 1944, 572 fighters lost.
June 1944, 611 fighters lost.
3 months, 1,672 German fighters destroyed.
50% of force.
Worse than aircraft losses, pilot losses.
Luftwaffa losing experienced pilots.
Men with 100 plus combat missions.
Irreplaceable veterans.
Replacements: teenagers, 20, 30 hours training, thrown into combat.
Life expectancy, two missions average.
Training infrastructure collapsing.
German flight schools under constant attack.
Mustangs strafing training bases.
Student pilots killed during practice.
Fuel shortages worsening.
Synthetic fuel plants bombed repeatedly.
German fighters grounded for lack of aviation fuel.
Vicious cycle.
Fewer pilots, less fuel, more losses, even fewer pilots.
By June 1944, Luftwaffa combat ineffective.
D-Day landings, June 6, 12,000 Allied aircraft, 319 Luftwafa aircraft responded.
Most fled without engaging.
Air superiority total.
Postwar interrogations revealed German perspective.
Goring Luftwafa commander refused to believe P-51 reports initially.
March 6, 1944.
German pilots reported single engine American fighters over Berlin.
Goring’s response.
Impossible.
American fighters cannot reach Berlin.
You are seeing damaged aircraft gliding from altitude.
March 8.
More reports.
Multiple squadrons.
P-51s dog fighting over city center.
Goring.
These reports are defeist lies.
American escort fighters have 400 mile range.
Berlin is 600 miles from England.
Physics prevents this.
Ordered investigation.
Intelligence officers collected evidence.
Drop tank remnants found in forests.
Paper construction.
108 capacity.
Analyzed manufacturing.
Calculated 108 external tanks plus internal fuel.
Range sufficient for Berlin mission.
Report presented to Goring.
His reaction according to witness Albert Spear threw report across room shouted that American technology propaganda refused to read analysis.
Goring’s deputy later wrote, “The day I saw mustangs over Berlin, I knew the war was lost.
Not because of the bombers, because the fighters had reached our capital.
It meant nowhere in Reich was safe.
We had no sanctuary, no place to train, no place to regroup.
The wolf was inside the house.
German pilots testimony consistent.
P-51 was superior fighter, faster than 109, more maneuverable than 190, longer range than anything German had.
JG77 commander.
We called it the Indian because it appeared everywhere.
You’d be over Munich.
Indian appeared over Vienna.
Indian over Budapest.
Indian.
No escape.
Postwar analysis.
Mustang’s arrival shortened war 612 months estimated.
Prevented development of jet fighters.
Prevented deployment of VWAP in numbers.
Saved estimated 500,11000 lives.
P-51 Mustang redefined air combat doctrine permanently.
Before fighter short-range interceptors defend territory, react to attacks.
After fighters longrange offensive weapons, seek enemy, destroy in depth, control airspace.
Every Air Force post 1945 adopted Mustang paradigm.
Korean War 195053 P-51 flew ground attack missions.
Proven design still effective 6 years later.
Doctrine influence continued longer.
F86 Saber direct descendant swept wings jet engine but same philosophy long range offensive capability pursue and destroy Vietnam era F4 Phantom designed as long range fighter bomber Mustang’s legacy modern F-15 F-16 F-22 all emphasize range speed offensive capability all trace lineage to P-51 paradigm shift engineering lessons aerody Aerodynamic efficiency matters.
Mustang’s laminer flow wing revolutionary influenced all subsequent fighter designs.
Engine airframe integration critical.
Right combination transforms capability.
Wrong combination wastess potential.
External fuel tanks now standard.
Every modern fighter carries drop tanks.
Concept pioneered by paper tank innovation 1944.
Disposable mission equipment accepted.
Missiles, bombs, tanks, all designed singleuse.
P-51 paper tanks proved concept worked.
Training implications.
Fighter pilots must think offensively.
Defense insufficient.
Must hunt enemy.
Range and endurance as important as speed and maneuverability.
Fuel management critical skill.
Longest range fighter useless if pilot runs dry.
P-51 created template modern fighter pilot follows.
