This is the SR-72 Son of Blackbird — it is faster than the fastest aircraft in history. A direct descendent of the SR-71 Blackbird, it was designed to fly faster and higher than every missile or cannon round shot at it. To say the least, the SR-72 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 SR-71 Blackbird.
