I flew on a MH
747-400 recently from KUL
and it was amazing to see from behind the wing the difference - before pushback the wings (being full of fuel) were bent down at the end, hardly giving enough room for the fuel truck that was there.
After landing, as we taxied in, we went past a BA
A320 and the wingtip was higher than we were in the cabin, higher than the A320 as well!
Quite interesting to see the difference!
