.1 mach is about 70-75 mph. Hornet couldn’t go that slow to track it.
I agree. I've watched the video and it doesn't look as if the thing was going that slow to me at all. The Hornet would have overtaken it in no time with as long as it was locked on....
But it was 2 miles up - probably at the end of it’s fuel supply. Five-foot wingspan is nice, though.
