>Landing over a city could be devastating to the cabin, buildings in the way, roads, power lines, etc.
Sheesh. I think everyone can see clearly from the vids that it's a magic flying cabin that steers itself under Parachute Power[tm] to the nearest baby-soft whispering green field, where it touches down with barely a ripple in anyone's coffee, and some mildly distracted clapping and cheering from the passengers.
It's a perfectly brilliant idea. Not stupid and pointless at all.
