That was great. I liked the U2 and SR-71. Me thinks that there is probably a pilotless Mach 3+ drone out there cloaked in secrecy in current use. One can't beat the intell from such a system. Satellites can't be everywhere at everytime.
Need some information? Can't beat a system that can go to point B from point A very quickly and when command needs the info like right now. I had read there is work on a Mach 6 recon plane.
