The sound barrier was a concept largely unexplored until the mid 40's. The pilots of some P-51, P-47, I-262, Ta-152 and other fighters of World War II noticed a strange aerodynamic effects when did minced long and caught a lot of speed. The sound barrier was officially broken exactly 60 years ago, the USAF pilot Charles Yeager in a Bell X1 rocket powered motor ... but that's another story. After breaking the record in the air, the challenge was to achieve at the surface and on wheels. The difficulties were considerable, especially on the power required and the stability of the vehicle. A Bugatti Veyron by little beyond 400 km / h with 1,001 horsepower, and when they want to get that speed, it takes a bestial power, much less is proportional. Hit a jump to 1997 in Black Rock, Nevada (USA). Andy Green is intended to break the sound barrier, and therefore the land speed record with the Thrust Super Sonic Car (SSC). I had no engine pistons (what we know for cars) but two ...
