When I was a kid the X-15 was a big flipping deal. Some have argued it was only a rocket engine with wings, not a plane. I thought they used a platinum screen as a catalyst. Why did they choose a narrator with such a pronounced speech impediment and accent. Can't stand hearing it. His frequency is horrendous. Bye.
