On December 17th, 1903, the Wright brothers flew the first aeroplane ever at 6.8 mph (10.9 km/h). Only 61 years and five days later, the Lockheed SR-71 Blackbird took off. It's still the world's fastest aeroplane with a speed of 2,193 mph (3,530 km/h.) This fascinating video explains its top secret engine technology.

It's truly amazing that only 61 years and five days separate this

And it's even more unbelievable that we haven't been able to top that 51 years later (it will be exactly 51 years tomorrow—the first flight occurred on December 22nd, 1963.) Absolutely incredible.
