Bob Timm and John Cook and the sixty-four day endurance flight over Las Vegas in a Cessna one seventy-two

In December 1958, slot machine mechanic Robert Timm and his partner John Cook took off from McCarran Field in Las Vegas in a stock 1958 Cessna 172 and didn’t land for 64 days, 22 hours, 19 minutes, and 5 seconds. That endurance flight record, set in the most ordinary training airplane ever built, has never been broken — and the Guinness Book of World Records eventually closed the category entirely to prevent anyone from dying in the attempt.

Why Would Anyone Try to Fly for Two Months Straight?

The existing endurance flight record in late 1958 stood at roughly 50 days. Timm believed he could beat it — not in a custom-built aircraft loaded with auxiliary fuel tanks, but in a bone-stock Skyhawk, the same airplane thousands of student pilots have used to earn their wings.

He partnered with John Cook, secured sponsorship from the Hacienda Hotel on the Las Vegas Strip, and registered the airplane as N9217B. The hotel’s name was painted across the fuselage, visible from the ground on every resupply pass. In exchange for the publicity, the Hacienda bankrolled the operation.

How Did They Refuel Without Landing?

The refueling method was as low-tech as it gets. Timm and Cook would fly low and slow over a straight stretch of desert highway south of Las Vegas while a truck drove underneath them, matching their speed. A crew member in the truck would hand up a fuel hose through the aircraft’s open door, and they’d pump gas into the airplane in flight.

Food, water, engine oil, clean clothes — everything came aboard the same way. A moving truck on a desert road, a Cessna 172 flying formation at roughly 60 miles per hour, and a handoff through the cabin door. This was not a military operation. It was two men, a truck, some rope, and an extraordinary amount of nerve.

What Kept the Airplane Running for 1,500 Hours?

The Continental O-300 flat-six engine ran continuously for over 1,500 hours without shutdown. Timm and Cook changed the oil in flight by draining it through a valve they’d installed in the sump, then pouring fresh oil in through the filler neck while the engine was still running. Spark plugs couldn’t be swapped, so they monitored engine temperatures obsessively, leaned the mixture carefully, and hoped.

That a production aircraft engine held together under those conditions remains one of the most remarkable testaments to the reliability of the Cessna 172 platform ever recorded.

What Was Daily Life Like Inside the Airplane?

The two men flew in shifts. One would pilot while the other attempted to sleep on a narrow cot rigged in the back of the cabin — a space anyone who has sat in a 172’s rear seats knows is barely adequate for a short flight, let alone weeks on end.

Daytime temperatures in the desert sun turned the aluminum cabin into an oven. Nighttime brought shivering cold at altitude. They couldn’t climb too high because they needed to stay near their refueling route, and they couldn’t stray far from Las Vegas because ground visibility was part of the publicity arrangement.

They flew a large racetrack pattern over the desert south of town, around the clock. Christmas 1958 dinner came out of a bag handed up from the truck. They rang in New Year’s Eve 1959 at four thousand feet above a city full of casino celebrations while they circled in the dark.

The Psychological and Physical Toll

The boredom proved more punishing than the physical discomfort. Timm and Cook exhausted every conversation topic within the first week. By the second week, they were barely speaking. By the third, Timm later recalled, the silence between them was oppressive — two men trapped in a space smaller than a bathroom, circling endlessly, unable to leave.

Timm was the visionary who refused to quit. Cook was the steadier hand who kept the airplane flying when exhaustion clouded Timm’s judgment. They argued. They went days without speaking. Then they reconciled, because there was nowhere else to go at five thousand feet over the Mojave.

Physically, their backs ached from the cramped seats. Their legs swelled from prolonged sitting. They lost weight on a diet of whatever could be passed through an airplane door from a truck doing fifty on a desert highway. Their skin dried out and their eyes burned from wind and dust that crept through every gap in the cabin.

The Landing and the Record That Still Stands

On February 7, 1959, Timm and Cook finally brought N9217B back to McCarran Field, rolling to a stop on the same runway they’d departed 64 days earlier. They could barely walk when they climbed out. Timm later said the most disorienting part was the silence — after more than two months of continuous engine noise, the quiet felt almost frightening.

The record has never been broken. Guinness eventually retired the endurance flight category to discourage potentially fatal attempts, which may be the most sensible decision the organization has ever made.

Where Is the Airplane Now?

The Cessna 172, N9217B, hung from the ceiling of the McCarran Airport terminal for years, where most travelers walked beneath it without a second glance. It was eventually removed, restored, and placed in a proper display befitting what it accomplished.

Why This Record Matters

Timm and Cook weren’t test pilots or military aviators. They were two ordinary men who attempted something absurd in the most common general aviation airplane ever manufactured — and succeeded through willpower, meticulous engine management, and a Continental flat-six that simply refused to quit. Their record stands as a tribute to human stubbornness and to the rugged reliability of the Cessna 172.
