This is really hard to look at...having spent 4 years on that flight line. All Riddle planes are secured with steel chains at 3 points at all times, 4 points would almost definitely have been in use if they saw this coming in on the radar....but I think the tie down rings would have ripped out of the airframe in a tornado anyway (as Danny pointed out, massive forces involved)....my God it will be months before its back to normal...
Thank god no one was killed.
