The Tupolev TU-144
This aircraft was originally intended for commercial usage. It had a space-age sleek design and already got the crowd talking. It could go from 0 to 1,200 in less time than most commercial planes of its era. Unfortunately, it was highly prone to turbulence and made for a very bumpy and scary ride. It was also extremely loud, especially on board. On its last voyage, the tank valve failed. They knew it was time.
