Bob Timm and John Cook and the Cessna one seventy-two that stayed airborne over Las Vegas for sixty-four days

In December 1958, slot machine mechanic Robert Timm and aircraft mechanic John Cook took off from McCarran Field in Las Vegas in a 1957 Cessna 172 and didn’t land for 64 days, 22 hours, and 19 minutes. Their endurance flight record, set with a stock airframe, a camp stove, and a bucket, has never been broken. Nearly seven decades later, it remains the longest continuous flight in aviation history.

How Did They Keep a Cessna 172 in the Air for 64 Days?

The airplane was tail number N5172B, powered by a 145-horsepower Continental O-300. The Hacienda Hotel and Casino sponsored the attempt, and Timm and Cook devised a remarkably low-tech refueling system to keep it flying.

Every twelve hours or so, a truck would drive down a straight stretch of highway outside Las Vegas. Timm or Cook would bring the Cessna down to roughly 50 feet above the desert floor, and a crew member in the truck bed would pass up a fuel hose. They hand-pumped avgas into a belly tank while flying at highway altitude over the Nevada desert. They repeated this procedure more than 100 times without a single mishap.

Food, supplies, and oil changes followed the same method. One pilot would fly while the other crawled into the back of the cabin, drained the engine oil through a line routed to the belly, and pumped in fresh oil — all in flight, in a Cessna 172 cockpit that barely has room to reach the back seat without kicking the yoke.

What Was Daily Life Like During the Flight?

Timm and Cook worked four-hour shifts. One flew while the other rested on a small mattress wedged behind the seats. They heated soup on a camp stove. There was no autopilot — one of them had hands on the controls every second for more than 1,500 hours.

The first week was almost enjoyable. The desert scenery cooperated, they settled into a routine, and the Hacienda milked the publicity. Reporters and crowds gathered at McCarran to watch the refueling runs.

By week two, the fatigue set in. The Continental O-300 droned without pause. The cabin reeked of oil, sweat, and whatever was heating on the stove. The two men started bickering — an inevitability when two adults share a space smaller than a bathroom for weeks on end.

By week three, the airplane itself was showing wear. Oil consumption crept up. The engine ran rough at times. Timm later described lying awake listening for any skip or hesitation in the engine’s rhythm, knowing there was no option to pull over.

What Challenges Nearly Ended the Flight?

Weather was a constant threat. Desert thunderstorms forced them to climb, dodge, and navigate around cells with no radar and no Stormscope — just their eyes and whatever information McCarran tower could relay by radio. One night, rain streamed through the door seals and pooled on the cabin floor.

Sleep deprivation became dangerous. Timm described catching himself staring at instruments without reading them. Cook reported moments of disorientation after waking up — forgetting where he was, briefly, while airborne over the desert in the dark.

And this was actually their second attempt. A previous try had ended early due to engine trouble. They could have walked away, but Timm was determined. They overhauled the engine, patched the airplane, and launched again.

When Did They Break the Record — and Why Didn’t They Land?

The existing endurance record was approximately 50 days, set in 1949 by a pair of pilots in a modified Aeronca Sedan over Fullerton, California. Timm and Cook passed that mark around day 50.

The Hacienda threw a party. Reporters celebrated. But Timm and Cook stayed airborne. Timm wanted a margin so large that no one would ever touch it.

They pushed through day 55, day 60, and beyond. The engine was tired. The airframe creaked in ways it hadn’t on day one. Every landing gear cycle during low refueling approaches made them hold their breath.

On February 7, 1959, they finally landed N5172B at McCarran Field and shut down the engine. Timm could barely stand — his legs had partially atrophied from weeks of sitting. Both men had lost weight and were sunburned, oil-stained, and completely spent.

Why Has No One Broken the Record?

The record has stood for over 65 years. In an era of composite airframes, fuel-injected engines, glass cockpits, and autopilots that outperform most human pilots, no one has mounted a serious challenge.

The Continental O-300 in N5172B ran for more than 1,500 continuous hours without a major failure. The airplane was eventually restored and displayed. Continental could not have asked for better proof of its engine’s durability.

What Makes This Story Matter to General Aviation?

The Cessna 172 is the most-produced airplane in history. It is the trainer, the family cruiser, the first airplane most pilots ever fly. Timm and Cook’s flight proved that the 172 was capable of something extraordinary — not because the machine was exceptional, but because the people flying it refused to quit.

This was not a story about cutting-edge technology, military contracts, or government programs. It was two working men who committed to something audacious and ground through it with stubbornness, endurance, and teamwork.

Robert Timm passed away in 1978. John Cook lived until 2008.

Key Takeaways

• Bob Timm and John Cook flew a stock 1957 Cessna 172 for 64 days, 22 hours, and 19 minutes from December 1958 to February 1959, setting an endurance record that still stands.
• They refueled by hand-pumping avgas from a truck driving below them on a desert highway, repeating the process over 100 times at roughly 50 feet AGL.
• The flight was their second attempt — engine trouble ended the first try, but they overhauled and relaunched.
• The Continental O-300 engine ran continuously for more than 1,500 hours without a major failure.
• Despite modern aviation technology, no one has come close to breaking their record in over six decades.
