6 times the speed of sound! The mach 7 North American X-15 reaches 4,520mph

Going fast is a great time and once you get into it, many will argue that you could even call it an addiction. Once you get a little taste of speed, you can’t help but want more almost like someone with a drug addiction. Sure, you say you are going to stop but let’s be honest, that day might just never come unless you run out of money entirely.

Even for the most hard-core enthusiast with the most money possible, there are certain limits to how fast their car can go but when you have NASA on your side, those limits go airborne and get stretch just a little bit farther to the point where speeds are reached that start to put the human body to the test.

This time, we check out a video behind how the experimental X-15 Space program gave birth to the fastest manned aircraft on Earth, reaching speeds of Mach 6.7. The craft would ultimately travel at a top speed of 4520 mph. That’s pretty much beyond the scope of what any of us could even begin to imagine.

Just when you thought that NHRA funny cars traveling in excess of 300 mph were a doozy, along came something fast enough to blow your mind into pieces if you think about it for long enough period of time.
