I think most people imagine these things buzzing around at treetop level but there's no reason not to go up a bit higher, just below aviation floors (500 feet in US I think). As long as it was at altitude a simple parachute could save it from a majority of (bad) crashes. It would only need a vertical "tunnel" to safely descend/ascend within.
