the 777 could takeoff and climb vertically and accelerate for a while if lightly loaded...
the 757 is overpowered... I LOVE IT!
the 777 if lightly load is EXTREMELY over powered AND I LOVE IT EVEN MORE! 230k lbs of thrust for a 326k lbs plane its GREAT!

the 57 and 77 are actually my favorite commerical planes ever, then third is the 737NG.
on all of these flybys these planes are loaded only for the demonstration, so they arent carrying that much fuel which is why they can do this. the NZAF does have a habit of showing off their 57's lol
