This is the SR72 Son of Blackbird — it is faster than the fastest aircraft in history. A direct descendent of the SR71 Blackbird, it was designed to fly faster and higher than every missile or cannon round shot at it. To say the least, the SR72 would be invincible. This aircraft, its predecessor, and its shocking, groundbreaking, nearby hypersonic cousin are the focus of this video — starting with the one that started it all — the SR71 Blackbird.
