Dude, chill out. No need to be a jerk. Continue it & we will deport you.

Especially don’t go shooting your mouth off when its clear you have absolutely zero knowledge what you are talking about.

For you to not even know air-to-air refueling is a thing, indicates you don’t know the first thing about aircraft at all. Like I know 4 year olds who know more about aircraft than you do.

That said; I do not know - but it could be found with a 5 second internet search - how long planes can fly before they absolutely HAVE to land, but it is very, VERY common for certain aircraft such as & especially B1, B2, B52s, to go on 48-hour or longer missions, where yes; they are in the air continuously, without landing once, for 48 hours or more.

There are hundreds if not thousands of examples of aircraft such as the ones I mentioned to take off from bases in the middle of the USA, fly to the Middle East, conduct operations in MULTIPLE locations thousands of miles away, and return back to that same US Air Base several days later.

I’m positive that an aircraft (actually there are 4 or more of these E4Bs but you sure don’t know that) as advanced and mission critical as the E4B has been modified so that it can stay in the air for prob at least a week or longer without having to touch ground once.

Chill out, take a breath, and maybe you can learn a thing or two.
