When Second Lieutenant Philip Rasmussen woke at Wheeler Field on the morning of December 7, 1941, he had no reason to believe that the clothes he was sleeping in would become part of one of the most enduring images of the attack on Pearl Harbor, because the Sunday morning had begun with the ordinary quiet of a military base that still considered itself at peace.
Before the day was over, Japanese bombs would crater the runways, American fighters would burn almost wingtip to wingtip, ships at Pearl Harbor would be shattered or sinking, and Rasmussen would return to the same airfield in a damaged fighter after surviving a battle that had begun before he had even managed to put on a uniform.
The transformation happened so quickly that preparation became almost meaningless, because men who had expected breakfast suddenly found themselves fighting for their lives while explosions rolled across Oahu.
Rasmussen had barely gotten out of bed when the noise changed from something confusing into something unmistakably violent, and although nobody around him yet possessed a complete picture of the attack, the sound of low aircraft and repeated explosions made one fact obvious enough.
The island was being attacked, and the aircraft overhead were not participating in an exercise.
While Japanese planes swept across Wheeler Field, Rasmussen ran toward the flight line without taking the time to change from his pajamas, because every minute spent dressing would be another minute during which the surviving American fighters could be destroyed on the ground.
The scene ahead of him looked increasingly hopeless as he approached, because Wheeler had been selected as one of the Japanese attack's crucial targets, and the reason was brutally logical.
If American fighters could be destroyed before their pilots got airborne, then the Japanese aircraft striking Pearl Harbor would face far less opposition over the fleet.
Rows of American planes therefore became targets before many engines had even started, while bombs and strafing fire turned portions of the field into smoke, flames, scattered equipment, and men running in several directions at once.
Most of the modern fighters around Rasmussen were either unavailable, damaged, exposed, or caught in the confusion, yet a handful of older Curtiss P-36 Hawks had survived well enough to offer something more valuable than technological superiority.
They offered the possibility of getting into the air.
Rasmussen climbed into one.
He was still wearing pajamas beneath whatever equipment he had managed to grab, while around him an airfield under attack was becoming the launch point for an improvised defense nobody had expected to need that morning.
The P-36 was not the fighter anyone would have chosen for a carefully planned interception against Mitsubishi A6M Zero fighters, because the Curtiss design represented an earlier stage of fighter development, and the Army Air Forces had already been replacing it with more modern machines such as the P-40.
Yet the best fighter in the world is useless while burning on the ground, whereas an older fighter that can take off still gives its pilot altitude, guns, maneuverability, and a chance.
Rasmussen and several other American pilots used that chance.
Among the men who managed to get airborne from Wheeler were Lieutenant Lewis Sanders, Lieutenant Gordon Sterling, and Lieutenant Harry Brown, while elsewhere on Oahu other pilots were also scrambling through the confusion and attempting to meet an enemy whose attack had achieved the surprise its planners wanted.
The four pilots from Wheeler were soon directed toward the vicinity of Kaneohe Bay, and although they had escaped the immediate destruction of the airfield, they were flying toward a situation that offered almost no comfort.
Eleven Japanese fighters were waiting in the area.
Four American pilots in hurriedly launched aircraft were about to meet them.
Rasmussen had left his bed only minutes earlier.
He had not been briefed for a combat mission, he had not climbed into the cockpit after studying an enemy formation, and he had not taken off as part of a carefully coordinated interception in which radar controllers, fighter directors, and ground crews had placed every element where it belonged.
Instead, he had entered a war while still wearing sleep clothes, and before the morning ended he would discover that surviving the takeoff had only delivered him to the more dangerous part of the story.
Wheeler Field Had Been Chosen for Destruction Before Rasmussen Ever Heard the First Explosion
The Japanese operation against Hawaii was not merely an attack against battleships, because Admiral Isoroku Yamamoto's planners understood that aircraft based on Oahu could interfere with the strike if they became airborne in significant numbers.
Wheeler Field therefore mattered enormously, because it housed important Army fighter units that might otherwise climb against the incoming Japanese formations.
The logic behind the attack was simple even though its execution required extraordinary coordination: damage the fleet at Pearl Harbor, suppress American aviation, strike other military facilities, and withdraw before Hawaii's defenders could organize an effective response.
For American pilots stationed at Wheeler, the problem began before they entered their cockpits, because peacetime assumptions had shaped how aircraft were parked and how readiness was maintained.
Fear of sabotage had influenced defensive precautions before December 7, and aircraft had often been positioned in ways that made guarding them easier on the ground, although those arrangements also made them dangerously vulnerable to air attack.
When Japanese aircraft arrived, closely parked American fighters offered concentrated targets, and the surprise attack converted administrative logic into battlefield exposure within minutes.
Rasmussen belonged to a generation of pilots who had trained while the United States moved gradually closer to war but had not yet experienced the opening shock personally, and although officers throughout the Pacific understood that conflict with Japan had become increasingly possible, possibility and actual bombs were separated by an enormous psychological distance.
That distance disappeared over Wheeler Field.
An airman who had gone to sleep inside an American military installation awoke inside a battlefield, while aircraft carrying the red sun insignia passed overhead and explosives struck facilities that had never before been treated as enemy targets.
The attack's speed mattered almost as much as its destructive power, because defenders needed time to identify what was happening, locate pilots, prepare aircraft, arm them, start engines, clear damaged areas, and establish some kind of command structure.
Japan's first wave tried to deny that time.
Rasmussen's response was therefore significant before he fired a single round, because simply getting an American fighter airborne required moving faster than the destruction spreading across the field.
The Curtiss P-36 Was Already Becoming Yesterday's Fighter
The P-36 Hawk had been an important American fighter when it entered service before the war, and its all-metal monoplane construction, enclosed cockpit, retractable landing gear, and relatively modern configuration represented a major advance over earlier biplanes.
Aviation development was moving so rapidly, however, that a fighter could appear modern and then become second-line equipment within only a few years.
By late 1941, the P-36 had been overshadowed by newer types, while combat in Europe and Asia had demonstrated how quickly speed, armament, armor protection, and engine performance were evolving.
The Mitsubishi Zero represented a particularly dangerous opponent, because Japanese naval aviators combined excellent training and substantial combat experience with an aircraft possessing exceptional range and impressive maneuverability.
A Zero pilot who entered battle with altitude, speed, and freedom to choose the engagement could exploit advantages that no American pilot wanted to concede.
Rasmussen did not have the luxury of selecting a better airplane, however, because combat does not pause while pilots compare specifications.
The P-36 that could still run was worth more than every damaged fighter Rasmussen could not use, and the very age of the Hawk may have contributed indirectly to its survival on the ground, because machines considered less immediately important could sometimes escape the concentration of destruction aimed at newer operational aircraft.
Once Rasmussen strapped himself inside, the debate over whether the P-36 was obsolete became irrelevant.
It had an engine.
It had functioning flight controls.
It carried guns.
The runway still existed well enough for takeoff.
Those facts were sufficient.
A Pilot Normally Builds Toward Combat, Whereas Rasmussen Was Thrown Into It
Combat aviation depends on preparation even when the fighting itself lasts only minutes, because pilots receive intelligence, study maps, check fuel, understand friendly formations, confirm radio procedures, inspect weather, and learn the mission objective before they leave the runway.
Rasmussen received almost none of that in the normal sequence, since the enemy had brought the mission directly to his base.
Instead of walking toward a fighter after a briefing, he ran toward one while parts of the installation were under attack, and rather than knowing the exact strength of the enemy force, he possessed the most basic possible instruction.
Get airborne and fight.
That kind of improvisation rewards habits built during training, because a pilot who has practiced emergency procedures, gunnery, formation work, aircraft handling, and recognition does not need to invent those skills while shells are exploding nearby.
Rasmussen's training could not tell him how to fight Pearl Harbor specifically, although it could give him enough automatic competence to start the engine, move the aircraft, take off, climb, and search for the enemy despite circumstances that threatened to overload every sense.
The pajamas later became the memorable detail because they illustrated how little warning he had received, yet the clothes mattered far less than the training underneath them.
A man can fight in pajamas if his hands still know the airplane.
Getting Off Wheeler Was Itself a Combat Action
As Rasmussen prepared the Hawk, Japanese aircraft were still active around Oahu, while smoke and damage complicated operations at Wheeler.
The pilot could not assume the runway would remain usable for another leisurely departure, and he could not know whether enemy fighters would strafe him before the wheels left the ground.
Starting a radial engine was normally a familiar process, yet familiarity changes when the pilot knows that remaining stationary makes him easier to kill.
Once the engine caught and the aircraft began moving, Rasmussen had to balance urgency with control, because destroying his own fighter through a rushed ground accident would accomplish the same result the enemy wanted.
The surviving pilots managed to launch, and the moment their wheels cleared the runway they entered an entirely different problem.
On the ground, the danger came from being stationary.
In the air, danger would come from Japanese pilots who had already spent years preparing for combat operations and who now possessed both numerical superiority and, in many cases, advantageous positions.
Rasmussen nevertheless gained something the burned American aircraft behind him no longer possessed.
Choice.
He could turn.
Climb.
Dive.
Fire.
Evade.
A functioning fighter restored agency, and on December 7 that alone was precious.
Oahu Had Become a Battlefield Larger Than Any One Pilot Could Understand
From the cockpit, Rasmussen could see fragments of catastrophe without understanding the entire attack, because smoke from Pearl Harbor and nearby installations marked places where events were unfolding faster than reports could travel.
Battleships were being hit.
Ford Island was under attack.
Kaneohe Naval Air Station had been struck.
Hickam Field was suffering heavy damage.
Aircraft burned at multiple bases.
Some American pilots attempted to get airborne from other locations, while anti-aircraft batteries began responding with varying degrees of coordination.
Nobody in Rasmussen's cockpit could provide a complete strategic picture, and he did not need one immediately.
A fighter pilot works inside a much smaller world.
Altitude.
Heading.
Fuel.
Other aircraft.
Sun position.
Clouds.
Radio calls.
Enemy movement.
The enormous attack on Hawaii would be reconstructed later by historians, commanders, survivors, and intelligence officers, whereas Rasmussen's task was to survive the next encounter.
When orders or vectors sent the Wheeler pilots toward Kaneohe Bay, their world narrowed further.
Japanese fighters were there.
That was enough.
Four Against Eleven Was Not a Ratio Any Pilot Would Choose
Numbers in air combat are deceptive because eleven aircraft cannot necessarily attack four targets simultaneously, while position, altitude, surprise, skill, and formation integrity can temporarily outweigh arithmetic.
Yet numbers still matter, because additional enemy fighters create more eyes, more guns, more opportunities for someone to enter a pilot's blind spot, and more pressure on every maneuver.
Rasmussen and the other American pilots therefore needed to avoid becoming isolated whenever possible, although the very nature of a swirling fighter engagement makes separation likely.
The P-36 had some useful characteristics despite its age, and at certain speeds it could maneuver effectively, while a skilled pilot could exploit turning ability, altitude changes, and brief firing opportunities rather than attempting to outrun aircraft that possessed stronger overall performance.
The Americans were not flying toward eleven stationary targets.
They were entering an environment where each Japanese pilot could maneuver independently, and where every American decision changed the geometry for everyone else.
A turn toward one Zero might expose Rasmussen to another.
A dive away from one attack might surrender altitude to three others.
A climb might save position or destroy energy.
Firing too early could waste ammunition, whereas waiting too long could let the target disappear.
This was not a shooting gallery.
It was a constantly changing three-dimensional problem in which decisions were measured in seconds.
The First Contact Destroyed Any Remaining Illusion of an Organized Interception
As the American pilots approached the Japanese formation, the engagement broke into individual contests almost immediately, because fighters do not remain neatly arranged once opponents begin turning, diving, firing, and crossing through one another's flight paths.
Rasmussen had little time to study what the other Americans were doing, although keeping track of Sanders, Sterling, and Brown remained important whenever the situation permitted.
The Japanese pilots reacted aggressively, and their numerical advantage allowed them to threaten the Americans from multiple directions.
A pilot in such a fight cannot stare at the aircraft directly ahead, because the enemy that kills him is frequently the one he never sees behind or above.
Rasmussen therefore had to divide attention between offensive opportunity and defensive survival, while the old Hawk demanded constant physical control.
There were no computerized warning systems.
No missile alerts.
No radar display inside the cockpit showing every hostile aircraft.
The pilot's eyes were the primary sensor.
His neck was part of the detection system.
His judgment became the fire-control computer.
When a Japanese fighter moved unexpectedly through Rasmussen's field of view, he had only a fraction of a second to determine whether the opportunity was genuine or whether following it would place him inside another pilot's guns.
That was the split-second nature of the battle.
Every move contained another move hidden behind it.
Rasmussen's Guns Added Their Own Problem at Exactly the Wrong Time
The P-36's armament offered far less firepower than later American fighters would carry, and any malfunction therefore became disproportionately serious.
During the engagement Rasmussen experienced trouble with his guns, and rather than possessing a large battery that could lose one weapon without dramatically reducing effectiveness, he found his offensive capability sharply limited.
Combat malfunctions create a brutal conflict of attention, because the pilot must continue flying the airplane and watching the enemy while also attempting to restore a weapon system.
Looking down for too long can be fatal.
Taking a hand away from normal control can be fatal.
Remaining focused on the jam while an enemy fighter crosses the nose can waste the best opportunity of the entire battle.
Rasmussen therefore had to work the problem without forgetting that the sky around him contained Japanese fighters actively trying to shoot him down.
Then an enemy aircraft moved into a position that created an immediate firing chance.
The decision could not wait for perfect mechanical conditions.
Whatever gun remained usable had to be enough.
Rasmussen fired.
The Japanese fighter went down.
The significance of the moment was not that one American suddenly balanced the entire battle, because he did not, while the fight around Kaneohe remained overwhelmingly dangerous.
Its importance lay elsewhere.
