At sea level it needs to travel at 340m/s.
carries fast
Only jet fighter planes break sound barrier now.
He broke the sound barrier October 14, 1947.
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.
It's around 1,125 FPS, BUT you really don't want to break the Sound Barrier. See the link below.
Of course. As his name suggests Sonic moves very fast, faster than the speed of sound and is able to break the sound barrier.
He has to travel at more than 760mph.
sonic boom as the planes speed exceeds the sound barrier.
The Spitfire could reach 606 mph .
The sound barrier to my knowledge, would be the buildup of energy as a plane or vehicle approaches the Speed of sound. It is also visible when something breaks the sound barrier. Check it out on youtube. It looks like a cloud. So in a way, anyway, it is a barrier, because it is harder to push through than if you were going 200mph.
About 340m/s at sea level
Any object traveling at a speed faster than sound will break the sound barrier. That is around 340 meters per second.
