re: Blazing speed is less useful for reconnaissance than many people think
How much damage could one do by simply whanging over a target (like ground troops) at, say, mach 5?
Anything?
It'd sure be fun (and scare the hell out somebody)!
I suppose the next thing to figure out how to do with UAVs is to refuel 'em in flight with another UAV. And if the situation called for it, used that fueled UAV tanker as a weapon in and of itself.
