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

Bob Timm and John Cook flew a stock 1958 Cessna 172 Skyhawk for 64 days, 22 hours, 19 minutes, and 5 seconds — the longest continuous flight in aviation history. They departed McCarran Field in Las Vegas on December 4, 1958, and did not touch the ground until February 7, 1959. The record has never been broken and stands as one of the oldest unbroken records in all of aviation, now past the 67-year mark.

Who Were Bob Timm and John Cook?

Timm was a slot machine repairman and pilot based in Las Vegas. Cook was a mechanic. The idea grew out of Timm’s fascination with endurance flight records from the 1920s and 1930s, when pilots in open-cockpit biplanes would fly circles over cities for days, refueling from cars on country roads. The existing light aircraft record was roughly 50 days.

Timm set out to beat it and raise money for the Damon Runyon Cancer Research Foundation. But ambition played a role too — he wanted to know if it could be done.

Why a Cessna 172?

The airplane was as ordinary as they come. A 1958 Cessna 172 with a 145-horsepower Continental O-300 engine, cruising at around 120 knots. They chose it precisely because it was common, tough, and parts were easy to source.

The modifications were practical, not exotic: an auxiliary fuel tank in the cabin, a belly tank for in-flight refueling, and a plywood platform over the right seat with a small mattress so one man could sleep while the other flew.

How Did They Refuel Without Landing?

The refueling system was the backbone of the operation. A ground crew drove a Ford truck fitted with a fuel tank and pump along a straight stretch of desert highway south of Las Vegas. Timm would bring the Skyhawk down to roughly five feet off the ground, flying in ground effect at 60 miles per hour, while the truck matched speed. A crew member standing in the truck bed passed up a fuel hose, and they pumped fuel into the belly tank.

They repeated this every 12 hours, day and night, for the entire flight. Food, water, oil, and supplies were passed up the same way — low over the road, grab the bag, climb back up.

What Was Daily Life Like Inside the Airplane?

The cabin of a Cessna 172 is smaller than a walk-in closet, and two men lived in it for over two months. They carried a small chemical toilet. The sleeping platform was roughly five feet long and two feet wide — no room to roll over or stretch out. The Continental flat-four engine hammered away 18 inches from their heads, continuously, for the entire flight.

After about three weeks, Timm said the hardest part wasn’t fatigue or boredom. It was the smell. Neither man ever fully described the cabin conditions in polite company.

The Nevada desert winter brought its own problems. Nighttime temperatures dropped sharply, and the Skyhawk’s heater was minimal. They wore heavy jackets and gloves and still shivered. Desert winds produced relentless turbulence in the light airplane, and there were nights when neither man could sleep.

How Did They Handle the Physical and Mental Toll?

Around the three-week mark, they hit what Timm called “the wall.” Everything hurt — backs, necks, knees. They developed sores from sitting in the same positions. Their appetites disappeared. They argued and stopped talking for hours at a stretch.

Cook later admitted there were moments he seriously considered demanding Timm land the airplane. He didn’t, but he thought about it.

Timm, as pilot in command, took responsibility for keeping the airplane airborne. He estimated he averaged roughly three hours of real sleep per night over the 64 days. Toward the end, he described a state of detachment where flying became automatic — holding altitude and heading without consciously thinking about it.

How Did the Engine Survive?

The Continental O-300 ran continuously for over 1,500 hours without a single shutdown — no cool-down, no rest. Oil consumption climbed steadily, and they added oil at every refueling stop. Spark plugs fouled. The engine gradually lost power: climb performance degraded and cruise speed dropped a few knots.

But the engine never quit. That sustained performance remains a striking testament to the engineering of Continental and Lycoming engines of that era, which were designed for roughly 2,000 hours between overhauls under normal operating conditions.

How Was the Record Verified?

The FAA, newly established in 1958 after replacing the Civil Aeronautics Administration, sent observers. The National Aeronautic Association (NAA) provided official timers. The airplane was inspected and sealed before departure, and the landing gear was painted with a special marker so any ground contact would be immediately visible.

What Happened When They Landed?

On February 7, 1959, at 2:27 PM local time, Timm and Cook landed back at McCarran Field. They had flown an estimated 150,000 miles. Both men needed help standing — their legs had partially atrophied from weeks of inactivity. Photographs from that day show them supported by ground crew members, unshaven, filthy, grinning, and squinting in the desert sun.

They raised some money for cancer research, though less than they had hoped. The fame faded quickly. Timm went back to fixing slot machines. Cook went back to turning wrenches. Neither attempted anything like it again. Timm later said that once was enough to know it could be done — and once was enough to know he never wanted to do it again.

Where Is the Airplane Now?

The original Cessna 172, tail number N9172B, is on display at Harry Reid International Airport (formerly McCarran International) in Las Vegas. It hangs from the ceiling near the baggage claim area with a small plaque. Most travelers walk right under it without looking up.

Key Takeaways

• Bob Timm and John Cook set the endurance flight record of 64 days, 22 hours, 19 minutes, and 5 seconds in a stock 1958 Cessna 172 — a record unbroken for over 67 years.
• Refueling was done in flight by flying in ground effect at 60 mph over a desert highway while a truck crew passed up fuel through a hose every 12 hours.
• The Continental O-300 engine ran continuously for over 1,500 hours without shutdown, a remarkable demonstration of the reliability of mid-century piston aircraft engines.
• The physical toll was severe: sleep deprivation, muscle atrophy, chronic pain, and psychological strain pushed both men to their limits.
• The airplane is preserved at Harry Reid International Airport in Las Vegas, where it hangs near the baggage claim — an easy stop for any pilot passing through.
