If you had a plane flying between DTW and say AMS back and forth with 1-2 hour turn around times could it just continue doing this for weeks/months/years if you have the cargo/passengers? Do airplanes need "down time"? Obviously if something mechanical happens it needs to be taken care of and if a plane is sitting it is bleeding money (as opposed to making money).
Insight? Thoughts? I just watched a youtube video following a Lufthansa cargo MD11 go around the world in 66 hours and I'm assuming it just kept going round and round with 2-3 hour stops the entire way.
