It is not the end, it is not even the beginning of the end, but it is, perhaps, the end of the beginning.

Sounds like an RC motor....maybe a fake?

Sounds fine to me, I've always known the 757's to have that sound effect. Being inside the 757 seems like being in a space shuttle almost on takeoff, even some pilots say "This is **insert callsign here**, ready for 'blastoff' ".

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! :x

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

Turbofan engines sound like that.

An airbus can't do a 1G barrel roll.  It can't do a roll of any type.  The limiters stop the roll somewhere before 60 deg angle of bank.  It's around 45 deg if I recall correctly.
Everyone I know, goes away, in the end.

Well ..

..I did a roll in a USAF B-52 sim at Castle AFB just to see if I could.
It was all about not exceeding the parameters of the equipment .. max level speed, pull nose up, start the roll as she goes up, and it took about 10k alt to complete it even so.
Not pretty and definitely not airshow material :)

The sim operator bet me I couldn't do it without exceeding something :)
I won the bet.

No they don't.  Those on a non Rolls Royce 757 (Pratt 2000), 767 (JT9D) and non GE powered Airbus 320s (CFM series) will sound like that.  The sound is the fan blades themselves hitting one another. There are blade bumpers installed on the engine to keep them spaced evenly and limit how much flex there is in the blades.

Rolls Royce Trent, GE-90 and CF-34s don't sound like that and they are without a doubt turbofan engines.  Their fan blade design has the blades spaced farther apart and never touch thus not requiring such a system.

If you had watched the second clip I posted you'd know that by pushing two buttons (shutting down two computers) the pilot can get direct law control over the ailerons and alternate law over the elevators, thus being able to barrel roll the aircraft. Of course, any pilot doing that in a real Airbus would not be a pilot for long. The bank angle limit of the A320 with normal law is 67 degrees; you'd know that too if you had watched the first clip I posted.

Prove that it can.  Even the Airbus instructor pilot casts doubt it can do a barrel roll in real life.  Nice try reaching at straws but you've failed.

Who's going to know better, you or someone that actually has hours flown in one?
