Let's see... first, a big ol' field for flying, with all the amenities. Much like others have already suggested. Also arrange for permanent Class F airspace overhead. Then, full-scale version of my avatar. The aft section is a Nike booster... the aircraft portion had a 6' wing span. Avro fired theirs into Lake Ontario (and some into the ocean from Wallops), but I'd make the plane R/C and have the booster recover via parachute. After that, maybe an upscale SSV Scorpion... flying on, oh I don't know... 98mm motors? Maybe an O?
