Are there any aircraft that can generate sufficient lift to get airborne without any forward movement.
That must have been a landing with no propeller movement. Or very little. It seems just the tips are a bit bent.

That fan wing is a very interesting design. Actually, the inventor reckons the design becomes more efficient as it becomes larger, and wants to scale-up the design.
The secret to vertical takeoff is you need to be able to make the airflow go straight downwards.I vaguely recall that there was an aircraft that took the airflow from the propulsion system and via a system of flaps could turn it downwards; once in flight they could change the flaps and it flew more normally. There was some problem with it though; I can't remember exactly I think the aircraft was quite heavy and unstable during takeoff.
