3 clips of the X-43 A that were on this page: https://www.nasa.gov/missions/research/x43-main.html

They are in .mov file format which is not supported by many operating systems today, so here they are on Youtube.
0:00 - Getting ready for Mach 10
1:14 - B-52B Takeoff
1:50 - X-43A Launch
The X-43A is the fastest Jet-Powered aircraft to this day, when it reached a speed of Mach 9.6 (7365mph/11854kmph).
It was dropped from a B-52B aircraft and then powered by a pegasus rocket, and then for about 10 seconds it burned a scramjet engine.
