RE: Zero speed landing possible ?
When I saw this thread the first thing I thought of was the routine step-off landings that paraglider pilots perform. They do it by pulling the trailing edge of the parasol wing down in a drastic arm gesture, effectively slowing airspeed to zero and stalling the wing just as their toes touch the ground.
Since this is a brainstorming thread I would throw out that perhaps you could design a wing that pivots about an axis just before touchdown. The extreme AoA would scrub forward speed without the craft zooming in an ideal world. Actual results may vary........
