How Fast Can The Fastest Plane Go?

The Lockheed sr-71 blackbird is, to date, the fastest plane ever built.

Top speed is above 2200 miles an hour - which is about 3 times the speed of sound and also can fly around 80000 feet which is 15 miles above earth.

It is said that at top speed the temperature is about 800 F degrees on the outside of the plane

The unmanned X-43 can go mach 9.8.

The fastest plane goes at mach 3+ its the sr 71 blackbird.it can fly over utah in 4 minutes

The record is 7460mph

1000mph

1.000

2000

1200 kph

2020m/s is the speed at which a fastest can go

Mach 8 for some old military fighters, that stopped working and costs tons of dollars ...

0.5mph...for toy planes that is but normal planes can get up to very high speeds of about 7000mph

Mikesude is right all speeds above the 3.2 M are for missiles or rockets like 8 M
1 M = 1225 kph

This dramatic picture was taken the moment this the B-2, officially named the Spirit Bomber is Fastest Plane in the World
