As much as I dream of someday being able to just buy a flying machine and go away flying it's unlikely to ever happen, not in the way these companies are envisioning it. I have this crazy vision about flying machines: Free direction takeoff. Not just horizontal takeoff; Warp drive propulsion: If lots of flying machines just fly in the same space-time plane it would become a mess, fast. Until science discover some way to warp the space/time around the machine it won't work; I'm talking hundreds of years till we get there; Guess my imagination is pretty fertile;
