Someone needs to check their figures. In order to circumnavigate the globe in one hour the craft would need to fly over three and a half times faster than its top speed!

Not only that, but it would have to be power diving aerodynamically all the way around, because even things in low Earth orbit take more like 90 minutes to go all the way around. Without air flow effects helping gravity hold it down, it would fly off into a much higher orbit if going 25,000 mph at 170,000 feet altitude.

Reading the article, this sounds like a "startup company" trying to get investors to give it money. Sounds like a bad risk, to me.
