If you didn't want someone to misconstrue, then why did you post a video of a passenger jet in the Cargo Forum? As other's have said, there was little to no wind during this landing (watch the windsock). Additionally, the smoke off the tires doesn't blow away ... it lingers. I wouldn't exactly call this extreme conditions. More so, this is Pilot Induced Oscillations (PIO).

What KC10 said. If I have to change my pants just watching this, wonder how those pilots are doing?

Good thing that wasn't built in Long Beach. Gear would've collapsed and a wing would've broken off.

Hmm . . . what landed before that one? Light quartering tailwind keeps the vortex on the runway the previous bird? Bueller? Bueller?

I was looking and trying to figure exactly how far down the runway the actual touchdown was, at least at the end of the touchdown zone. However, from the response of the aircraft, a sinking/rolling motion, I agree that it was probably a case of wake turbulence that caused this touchdown.
