well, Glen, I dunno... I've had difficulty adjusting my eyeline from K8/K13/K21 arse on ground to Rollason Condor arse at potty height....
I could probably manage a circuit in a glider from cockpit elevation of a large jet at touchdown....
So if there is a machine that can do a better job, I'd use it.
