SpaceX Starship
On 2 February 2021, SN9 flew  high. During the landing, a Raptor does not work. So, SN9 lands at an angle and exploded as well. On 3 March 2021, SN10 repeated SN9's flight. It then landed with all Raptors working. But, because SN10 was damaged, it blew up eight minutes later. On 8 March 2021, the first Super Heavy booster named BN1 (booster number 1) was finished.
