About 340m/s at sea level
At sea level it needs to travel at 340m/s.
Some rocket planes can go as fast as six times the speed of sound. Most military fighter planes do not go faster than twice the speed of sound, and the typical civilian passenger/transport plane goes slower than the sound barrier.
I believe it is the SR-71 Blackbird, it goes about mach 3.2 or three times the speed of sound.
no
The fastest plane was the Blackbird and it flew at 2500 mph.
depends on the plane.
600 mph
9000mph
A fast train can be faster than a slow plane. But even a regular plane will be faster than fast train.
Early versions could go 354mph
Mach 3 is three times the speed of sound, or roughly 2,280mph at sea level or roughly 2,000mph at altitude as the speed of sound is dependent on air density and temperature.
1500
