There are claims that the P-47 did, but if so it would only have been in a steep dive and the plane would not have been controllable while supersonic.
BellX-1
The Concord only broke the SOUND barrier, as do many aircraft still flying today, which has no effect on Time. To break a TIME barrier (in theory anyway) you have to travel faster than the speed of light.
The Bell X-1 rocket plane first exceeded the speed of sound on 19 January 1946. The piolet reported big problems with serious shaking of the aircraft that we now understand to be as a result of the sonic boom
Thrust SSC was the first car to break the sound barrier. Thrust SSC is a British designed jet propelled car developed by Richard Noble, Glynne Bowsher, Ron Ayers and Jeremy Bliss. Thrust SSC broke the land speed record on 15th October 1997 piloted by RAF Squadron Leader Andy Green and traveled at 1228km/h, a record which still stands today.
Yes you can change the speed of sound. IF you change the medium the speed changes. IF you change the density of the medium it changes. IF you change the temperature of the medium the speed changes.
depending on the size of the object that broke the sound barrier a whip for example does almost nothing but a fighter jets sonic boom could be loud enough to break glass make you deaf or possibly even kill you if your close enough.
Chuck Yeager broke the sound barrier in 1947 flying the experimental X-1 aircraft.
The first breaking of the sound barrier was during World War 2. One can find more information from Wikipedia. By 1950s, new aircraft broke the sound barrier.
The Concord only broke the SOUND barrier, as do many aircraft still flying today, which has no effect on Time. To break a TIME barrier (in theory anyway) you have to travel faster than the speed of light.
Marion Motley in 1946. Fullback for the Cleveland Browns
which processor fist broke the 10oMHz
Jackie Cochran
No one broke the color barrier in 1946, however in 1947 Jackie Robinson broke it by playing for the Brooklyn Dodgers.
chuck yeager
The whip.
that he broke the color barrier
Chuck Yeager piloted the plane that broke the sound barrier, but he didn't invent it.
He broke the sound barrier October 14, 1947.
