What is peculiarly though is that these craft would be flying so close to our jets as to endanger their (the pilots') safety.
Think about it this way. A 30-06 can fire a round that is multiples the speed of sound.
I wouldn’t put it beyond our technology to have small near-super-sonic craft, or even super-sonic craft.
I think the Russians are way behind on their hypersonic tech — they are using nuclear. I think we have a better way, and that energy storage medium is trickling down to smaller craft.
Plus, the military never bothers with Pilot safety when it comes to the new stuff. I mean, they do, but they recruit a breed of folks who don’t mind living on the edge. Even fighter pilots fall in that category.
Fighter planes don’t glide very much at all, they fall like bricks basically. So you are betting each time out that the engines, or at least a engine, will stay online.
If anything we’ve learned from commercial aviation that is a big bet :)
