The SR-71 Blackbird was the fastest military jet that has ever taken to the skies. But there was a plane that not only went twice as fast, but it also went much higher.

That speedy plane was the North American X-15.

The X-15 was one of the first true spaceplanes, with a number of flights going beyond Earth’s atmosphere, according to a 2005 NASA release. It was capable of going over 4,500 mph, or nearly Mach 6, and it went as high as 354,200 feet – or just over 67 miles – above the Earth.

The X-15 was launched from a B-52, its engines burned for 2 minutes or less, and the rest of its 10 or 20 minute flight, including landing, it was gliding.

The SR-71 took off under its own power, could be refueled multiple times, and was performing powered flight for however many hours its mission required.

Not even an apples-pineapples comparison.

Good points.
