The Wright Field Crash That Created Aviation Checklists
A small slip-up at Wright Field in 1935 changed air travel forever. On October 30, Boeing’s new Model 299 bomber took off with Major Ployer Hill at the controls.
The plane shot up, stalled, then crashed in flames. Both Hill and Boeing’s test pilot Leslie Tower died from their wounds.
The cause? They’d simply forgotten to unlock the tail controls.
Critics called Boeing’s "Flying Fortress" too complex to fly. In response, Boeing made a simple tool – the pilot’s checklist.
This humble paper saved the B-17 program and now keeps millions safe in the skies. The National Museum of the USAF in Ohio showcases this story where aviation safety truly began.

One Forgotten Lock Caused a Deadly Boeing Crash
The Boeing Model 299 took off from Wright Field near Dayton, Ohio on October 30, 1935. Major Ployer P.
Hill from the Army Air Corps sat at the controls for his first flight in this plane. Boeing’s chief test pilot Leslie Tower joined him in the cockpit.
The huge four-engine bomber, later known as the B-17 Flying Fortress, climbed into the sky. Seconds later, something went wrong.
The plane shot upward, stalled, and crashed to the ground in flames.

The Fatal Mistake That Changed Aviation Forever
A simple oversight caused the crash. The crew forgot to unlock the gust locks, devices that held the tail surfaces while the plane sat parked. These locks stopped wind damage but made flying impossible.
The crash team found the control locks still locked after the wreckage cooled. Despite brave rescue efforts by Lieutenant Robert K.
Giovannoli, who rushed into the burning plane, both pilots got fatal injuries and died in the hospital.

Critics Called Boeing’s New Bomber "Too Complex to Fly"
Newspapers blasted the Model 299 after the crash. Military officials wondered if pilots could safely handle such an advanced plane.
The bomber had four engines when most military planes had one or two. It carried multiple machine guns, complex bomb gear, and new flight systems.
Critics said humans couldn’t handle so many controls safely. The crash put Boeing’s chances of winning the big military contract they badly needed at risk.

Boeing Engineers Found a Simple Solution to a Complex Problem
Boeing’s team refused to accept their plane was too hard to fly. They gathered test pilots and engineers to find an answer.
The solution wasn’t changing the plane or adding more tech – it was creating a simple checklist. They listed every step needed for takeoff, flight, and landing on a card pilots could follow.
The idea came from factory quality checks but had never been used in flying planes before.

The First Aviation Checklist Fit on a 4×7 Card
The original Boeing checklist looked nothing like today’s thick manuals. It fit on a single 4×7 inch card with simple items pilots could check quickly.
The list included basics like "Brakes – Released" and "Control Locks – Off. " Pilots went through each item step by step before takeoff, during flight, and before landing.
This simple tool made sure no key steps were missed, no matter how much flying experience a pilot had.

Military Pilots Flew 1.8 Million Miles Without Incident
The Army gave Boeing another chance, ordering 13 test models of the bomber. Pilots using the new checklists flew these planes 1.
8 million miles without a single crash. The military liked what they saw.
They placed orders for what would become the famous B-17 Flying Fortress.
The checklist showed that normal pilots, not just the best flyers with perfect memories, could safely fly complex planes.

Checklists Spread Beyond Boeing to All Aircraft
Other plane makers quickly copied Boeing’s idea. By 1937, most military and commercial planes used some kind of checklist.
The tool became standard in pilot training programs worldwide.
Makers designed cockpits with checklist use in mind, grouping controls in a logical order to match the steps.
The flying world saw that human memory, even with good training, needed backup systems to stop deadly mistakes.

The Paper Tool That Made Modern Aviation Possible
Without checklists, today’s commercial flying might not exist. Modern airliners have thousands of systems that need exact operation.
No pilot, no matter how skilled, can remember every step for every situation. The simple checklist allows normal humans to safely fly very complex machines.
Each time you get on a commercial flight, the pilots use updated versions of that first Boeing checklist from 1935.

Doctors Borrowed the Idea to Save Lives in Hospitals
The checklist idea jumped from cockpits to operating rooms in the early 2000s. Surgeon Atul Gawande pushed for surgical checklists after studying flight safety.
Hospitals using these tools saw big drops in problems and deaths.
The same idea that saved pilots from forgotten control locks now protects patients from surgical errors. The Boeing crash tragedy ended up saving countless lives beyond just flying.

A Simple Tool Born From Tragedy Still Saves Lives Today
The Boeing Model 299 crash killed two talented pilots but created a safety revolution. Every time a pilot reaches for a checklist, they honor the legacy of Major Hill and Leslie Tower.
The checklist transformed a "too complex to fly" aircraft into one of history’s most successful bombers. Boeing’s response to tragedy became aviation’s most important safety innovation.
This simple paper tool, born from disaster, continues saving lives nearly 90 years after that fateful day at Wright Field.

Visiting B-17 Flying Fortress, Ohio
The National Museum of the U. S.
Air Force at Wright-Patterson Air Force Base houses B-17 Flying Fortress displays that tell the story of the 1935 Boeing Model 299 crash.
This tragedy led to aviation checklists after pilots forgot to remove control locks during takeoff. You can visit for free daily from 9am-5pm at 1100 Spaatz Street in Dayton.
The World War II Gallery shows how this accident changed aviation safety forever, plus you’ll see over 360 aircraft and missiles throughout the museum.
