The tech, if one could pull it off, would be amazing.

Heck, think of the huge sums of money one could make on military applications alone for an unmanned VSTOL that could take off, fly 50 miles (or more) and then land, unassisted, with an accuracy of five feet of its aimpoint.

We can't even get automated ground vehicles to navigate that far reliably, and they don't have to deal with gusts, thermals, wind, etc.
