The aircraft is hanging from the ceiling at the Las Vegas airport along with displays of artifacts from the flight. One of those things people just walk past and don’t pay attention to, but worth a look if you’re there!

It would help putting a big sign pointing at the plane and explaining what it did once.

For me, it's crazy they were able to stay that long time with the engine noise. Also, there's no that much space to stretch and doing some exercise. As the article says, most likely there aren't more people who want to try to beat it.

It really likely is one of those "never will be beaten" records because anyone sane would do it in a B-52 bomber and have some room to stretch out - but everyone would immediately know it wasn't quite as "real" as being stuck in a plane the size of a Volkswagen bug for 2 months.

According to [1] Fédération Aéronautique Internationale stopped recognizing piloted endurance records altogether in 2015 due to safety concerns.

So I'd say this record is very unlikely to be beaten!

Pilots are truly some of the craziest people around. Just last summer, a guy flew a Cessna 172 from California to Hawaii. https://flightaware.com/live/flight/N490NW/history/20220820/...

People fly small single engined planes from Nunavut to Greenland to Europe on a fairly regular basis.

This is by far the most interesting part of the story:

> Refuelling was handled by lowering a hook via a winch down to a fuel truck that would trail the plane on a straight stretch of road, usually twice a day. The winch would then pull up a fuel hose from the truck, which would be used to fill the belly tank in around three minutes. The same system was used to regularly pull up food, oil and other supplies like towels and water for shaving and bathing.

Midair refueling is the realm of air forces and these guys did it with a hook on a winch.

> 1,800 hours time-before-overhaul That’s surprising! Do you mean the entire life of the engine, or just one run? If the former, doesn’t that get expensive? I imagine that’s not very sustainable.

Entire life of the engine. After 1800 hours total operation, the engine should be overhauled: taken apart, cleaned, each part examined and replaced if necessary. Note that per FAA regulations in the USA, only actual flight time counts toward this limit, not time spent taxiing on the ground. It'll take a normal private pilot a few years to reach 1800h of operation, so it's more economical if you're not flying the plan…

Electric airplanes are already used in training in Europe. They are less expensive to operate on an hourly basis just because of fuel/energy cost. But they are probably also cheaper to overhaul; the Emrax motors in Pipistrels are relatively simple, and it would probably cost less to buy two and swap one out (sending the other one back to Emrax for a new bearings) than to do one thermal engine overhaul. And almost no downtime!

(I work on another electric airplane which will take flight in 2023.)

Earlier quoted context omitted.

In a car running at 100 kph, that would be 180000 km (roughly 110 miles). Most cars would need at least some parts replaced by that time as well..

Yet only 54000 km at the more typical average speed of 30 km/h. Are aircraft engines typically under high load at cruising speeds? It would seem they are generally overbuilt to overcome the high demands of takeoff.

I think they are under more of a load a cruising speed than you'd expect. At speed both the car and plane are primarily overcoming wind resistance, which is more about speed and elevation than anything. If I'm understanding right the plane would be going more than highway speed within a few thousand feet of the ground for most of it's (flying) life so it's probably putting more stress on the engine than a car on the highway would.

More importantly: if your car engine dies you gradually slow down and pull over. If your plane engine dies calmly pulling over isn't an option. It's much easier to justify spending the money ensuring a plane's engine is reliable.

I think you have a typo at the start of your second paragraph. Fairly certain you're calling out the few planes that are inherently UNstable there :)

thanks, that made my whole comment hard to understand

For what it's worth I found your whole comment easy to understand because it was well constructed and very logical, so much so that I didn't even notice the typo because your intent was so clear that I subconsciously auto-corrected it.

I asked my dad what they did on a long (8+ hours) bombing mission in WW2 when nature calls (a subject never covered by documentaries). He said "we used empty ammo boxes". I asked what they then did with the ammo boxes. He said "extra bombs".

That’s a real crap shoot.
