Ahhhhh why not
Long time ago, when research in sims was still possible (Pre 9/11), we had a few minutes spare at the end of a slot, so we tried putting a very light 747-400 into Chicago Meigs, ( Of Flight simulator fame) with no special wind to make it simple.
It was tight, but it fitted. What was even more "interesting" was getting it out again.
I can't recall now if the fuel load was legal, but it got out, and we got it around the corner back to a more civilised size strip, but it for sure was a bit of fun.
Seriously, short field training does help refine the technique, if there's a couple of miles of tarmac ahead, it's all to easy to have a "somewhere down there" attitude, and that doesn't help when it has to be fitted somewhere small without the option.
A friend of mine sent me some very impressive pics a while back of a South African 747 being retired to a small strip, so they planned it very carefully, and made it fit there too, and very pretty it looked as well.
