Are you sure you don't mean _delay_ crashing?
Sail planes with proper cammy would be a great,l really stealthy recon asset--just don't get noticed, don't get fired at, and especially don't get hit.
How about a towed steerable parachute connected to its tow vehicle by a releasable cable. You'd just need a sufficiently straight stretch of road to build up speed and height.
If a winch itself is too slow, why not a drop-weight catapult, using the winch to hoist the counterweight back up again?
