I like the PAL-V, in concept; we’ll have to wait and see what reality makes of it. An unnamed bureaucrat somewhere doubtless has a spanner in their desk drawer with which to foul up the works.
Now, if we can find him in time, we can blast him before he can do any damage.
Obviously, my position is that bureaucrats ought to be listed as a game species.
I like the PAL-V concept and it's Earth-bound cousin the Carver. Seems to be a lot more feasible as a commuter solution than the Air-Scooter, Trek Aerospace's Sprintail, or the Moller Skycar.
