Not really and not funny either, just a good lesson on why tie downs are a good idea..... http://izismile.com/2011/11/16/its_impressive_what_strong_winds_can_cause.html Sorry not able to embed.
Wow that blew me away, excuse the pun. Not quite what I expected to see. Wonder where the liability laid presuming a jet is doing run ups. I would presume whoever parked first would be in the right provided they parked in a designated area. Imagine just landing & finding the need to urgently visit the gents or ladies & doing a quick run to return to find that! Ouch!
I reckon you guys have called it right, not enough other movement for it to be wind. I saw the same thing discussed elsewhere last night, not having watched in fullscreen I missed the fact that there were actually tiedowns involved - they broke Maybe time to rethink the miserable bits of clothesline so many people seem to use, plus they deteriorate in the sunlight, some of them pretty quickly.
