Often wondered about this one - say for example you wanted to drop someone off at the beach or on the end of a pier or on a Tor on Dartmoor or in the middle of a large roundabout...(!)
If you DO land, you'll probably make the papers and incur the wrath of whoever owns the land although as long as you leave when asked and the area is unfenced then trespassing shouldn't be an option - and the fact that you're landing means you CAN fly closer than 500' to people or property.
If you DON'T land, and opt for a hovering exit, then obviously land owners permission and trespassing isn't an issue - but because you don't touch skids, you're not landing and therefore can't fly closer than 500' to the person you just dropped off!
The sooner theres a pad on the roof of every Debenhams, the better I say.
