On the morning of 4 December 1958, two men climbed into a slightly modified, four-seat Cessna 172 at McCarran Field on the southern edge of Las Vegas. The airplane was painted in the cream-and-script livery of the Hacienda Hotel, a Strip resort that had decided, for reasons we will get to, that the most cost-effective way to advertise itself was to keep an airplane in the sky for as long as humanly possible. The two men were Robert Timm — a slot-machine mechanic at the Hacienda who, before the slot machines, had been an Army Air Corps bomber pilot — and John Wayne Cook, a working flight instructor who would do most of the actual flying.

They lifted off. Then they did not land for sixty-four days, twenty-two hours, and nineteen minutes.

That record, set by two ordinary men in a stock-frame Cessna 172 with a slightly oversized belly tank and a great deal of patience, still stands today. Sixty-seven years later, no one has come within a country mile of beating it. Nobody, in fact, has ever seriously tried. And the airplane that did it — registration N9217B, the Hacienda — is still hanging from the ceiling at the baggage-claim level of Harry Reid International Airport, the modern incarnation of the old McCarran Field, where every traveller flying into Las Vegas walks underneath the most absurd aviation record in history without ever knowing it’s there.

A Slot-Machine Mechanic Decides to Set a World Record

The story really begins with Doc Bailey, the owner of the Hacienda, a hotel-casino on the very southern end of the Las Vegas Strip with — by Vegas standards — a credibility problem. It was 1958. The Hacienda was newer than the Sands, less famous than the Flamingo, and farther from the action than the Sahara. Doc Bailey had marketing money to spend and a dwindling list of ideas. He had recently funded a much shorter publicity flight by Bob Timm, his slot-machine mechanic, who happened to fly. The flight had ended badly when the engine seized over Arizona. Bailey, being a Vegas operator, decided the only sensible response was to try again, but bigger.

Timm proposed they go for the unrefueled flight endurance record. The current mark was 50 days, set by another publicity-stunt crew over Texas. Bailey budgeted $100,000 — real money in 1958, equivalent to over a million today — and Timm got to work. He bought a used 1956 Cessna 172, ripped out the right seat and replaced it with a foam mattress, removed the cabin door on the co-pilot side and replaced it with a winch-operated cargo door, plumbed a 95-gallon belly tank to the wing tanks via an electric transfer pump, and rigged a steel hook on a hose for in-flight refuelling. Power came from the stock Continental O-300 six-cylinder air-cooled engine. There was no special engine. The whole point of the exercise was that the airplane was, mechanically, almost completely stock.

The refuelling rig is the part of this story that most people, on hearing it, refuse to believe. There was no Boeing KC-135 involved. There was no tanker. The Hacienda was refuelled twice a day, dawn and dusk, by a 1956 Ford Country Sedan station wagon racing down a closed-off stretch of US Highway 91 in the Mojave Desert. Timm or Cook would dive the airplane to within twenty feet of the road; the station wagon would pin the throttle at exactly the airplane’s stall speed of around 80 mph; the chase-car driver would hold a hose up out of the rear window. Cook, lying on his belly with his arm through the cargo opening, would lower the steel hook on its own hose and try to snag the chase car’s hose. When it caught, he’d reel it in, jam the nozzle into the airplane’s belly-tank inlet, and pump fuel up at altitude.

This happened every single morning and every single evening for two months.

Sixty-Four Days in a Four-Seat Cessna

The cabin of a Cessna 172 is, generously, the size of a compact sedan. Cook and Timm shared it for over two months. They rotated in four-hour shifts — one flying, one off-duty in the back — with the off-duty pilot stretched on the foam mattress where the right seat had been. Sleep was earplugs, a blanket, and the constant six-cylinder thrum of the O-300 about a metre from your skull. Meals were hot food in thermos flasks, hoisted up from the station wagon along with the fuel hose, twice a day. A bath was a sponge and a bucket of warm water at six thousand feet over the Mojave.

The bathroom — and people always want to know about the bathroom — was a hatch in the cabin floor and a chemical bucket. The Hacienda’s PR people pointedly did not publish photos of this part of the operation.

The Cessna’s engine ran continuously. Timm and Cook started swapping oil filters mid-flight from the inside of the cabin, by leaning out through the cargo door with a wrench and a fresh filter; they did the same with spark plugs. At one point, around day forty, an alternator failure took out the cabin lights and the electric fuel pump. They flew the rest of the way using a hand-crank backup pump and, at night, a flashlight Cook held in his teeth.

By the time they landed on 7 February 1959 at McCarran, the wheels of N9217B had not touched the ground since the previous calendar year. The engine had run for 1,558 hours straight — roughly the same number of operating hours most general-aviation engines see in five years of normal use. The aircraft was filthy, the men were exhausted, and the Hacienda had a publicity stunt that, six decades later, is still cited as the longest unrefuelled-by-tanker flight in history.

Why No One Has Ever Beaten It

The Timm-Cook record is unusual among aviation records in that it is fully accessible — you don’t need a hypersonic vehicle or a billionaire’s helium budget to attempt it. You need a Cessna, a friend, and a station wagon. And yet, in 67 years, no one has.

The first reason is that the FAA, which did not exist as a body in 1958 — the rules were enforced by the older Civil Aeronautics Authority — would now object, vigorously, to a publicity stunt that involves an airplane flying twenty feet above a public highway at stall speed twice a day for two months. The second reason is that modern liability insurance does not exist for this sort of thing. The third reason is that the only people who would actually attempt it are, by definition, the sort of people the FAA already keeps an eye on.

But the deepest reason is the one Timm himself gave: nobody who has tried it ever wants to do it again. The boredom of the middle three weeks — once the novelty had worn off, once the press had stopped paying attention, once the days had blurred into an endless cycle of station-wagon refuellings — was, in his own estimation, worse than the engine failures.

The Airplane Is Still There

If you fly into Harry Reid International Airport today, walk to baggage claim. Look up. Hanging from the ceiling, beautifully restored, is N9217B. The Hacienda Hotel itself was demolished in 1996 to make way for the Mandalay Bay. The slot-machine mechanic who flew the airplane died in 1976, his co-pilot in 1995. But the Cessna is still there, suspended over a sea of rolling suitcases and rental-car kiosks, looking exactly the way it did when it taxied in for the last time in February 1959. Most travellers walk under it without noticing.

Which is, in its own quiet way, the most American thing about it. The longest flight ever made by anyone, in any aircraft, anywhere, in the history of human aviation — and we hung it from the ceiling of an arrivals hall.
