Depends on the aircraft. For example, an F-18 kind of sounds like howl or moan that starts off low and get high until you here the above mentioned noise. The F-15 has a very annoying, high pitched, squeel after it has started but not when it is flying.
There are a lot of companies that make jet aircraft. There are two big ones, Airbus and Boeing.
Quite a lot of things can outrun the speed of sound: - rifle bullets - rockets launching stuff into orbit - a couple of jet or rocket cars - The Concorde passenger jet - Fighter Aircraft - Anti-Aircraft missiles
Aircraft that can break the sound barrier, yes they are jets. Aircraft are jets if they are powered by jet engines, as opposed to piston engines which have propellers.
It depends on whether the mechanic works on jet aircraft, or non-jet aircraft. For non-jet aircraft, a mean annual salary would be around $55 000 a year, for jet aircraft, it would be more like $75 000 a year.
These days passenger jet aircraft are the norm
Frank Whittle invented the Jet Aircraft.
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
An aircraft propelled by jet engines rather than piston engines.
No jet aircraft were used in WW1.
