most military air combat jet aircraft can go over mach 1.0, passenger aircraft fly at around mach 0.80
The manufacturers admit to 1,400 mph, -personally, I would not be surprised if it was higher than that.
Cadillac division of General Motors is NOT an aircraft maker.
It depends on the jet or aircraft you are refering too some go into our atmosphere
There is no such thing as a jet train.
very fast
Frank Whittle invented the Jet Aircraft.
On an aircraft carrier, 0 to 60 mph in 2.5 seconds.
Enough to propel the aircraft very fast through the air.
The world's fasted jet-powered aircraft is the SR-71 Blackbird. This jet can flay more than Mach 3.3 (3.3 times the speed of sound).
I think Jet Airways have 97 Aircraft
depends on the aircraft.
