This amateur 'stunt pilot' stuff can sure get you fired these days, for example:
Top British pilot fired for performing 320mph 'fly-by' just 28 feet from the ground - in a jumbo full of VIPs | Daily Mail Online
I believe the Cathay flight and the one yesterday departed Paine Field, KPAE not Boeing Field, KBFI, they both have large Boeing facilities.
The B-748 wing rock right after liftoff is not a normal maneuver and should at the very least get a letter from the feds I would think. Or maybe the Bud Holland Memorial Airshow Award.
