Recently the news has been reporting on a $54 million request to replace the aging refrigerators on Air Force One. Some discussion has been had as to why AF1 even needs 3000 meals on board. Taking a 130ish person compliment times 3 meals a day, the math suggests that this would last them 7.7 days. It stands to reason that this 3000 meal number comes from some kind of directive stating that there be 7 days worth of food on board, with some conservative up rounding to get the number to an even 3000.
No jumbo jet seems to have ever flown more than 24 hours, and most endurance flights seem to have been on small prop driven aircraft, some with features such as the ability to perform an oil change mid flight.
Even with mid air refueling, and engine rotation /resting, how long could a jumbo jet stay in the sky?
