I'd say the first one is real. I've seen model planes get lifted like that from a gust.
A couple times I've been out at FAI when a thunderstorm kicked up with high winds. Twice I was at my mechanic's and the owner grabbed a handfull of tiedown ropes and we ran up the ramp tying down planes.
One that baffles me is all the taildraggers that have no chocks, no parking brake and only the wings tied down loosly. What can happen is a wind from behind lifts the tail and dumps the plane on it's nose, or pulls the wings back as the plane rolls forward. Or wose, a side wind causes it to pivot into the next plane over. These guys payed for a $80k super cub, but can't bother to use $20 worth of rope and chocks to protect it?!
