Sheesh!
Is this the recommended x-wind landing technique? They didn't seem to make any attempt to kick 'em straight - perhaps this was a test of sideways loads on the gear?
I've seen similar x-wind techniques at BK, in a 152

They can't really do the 'wing down' xwind technique, there are big engine-thingies in the way...

Believe that even more than 35kts can be done in a 744.....wouldn't like to say who did it though.

Hows about that inspirational music that goes with it.
Just makes me want to get up there and start landing in a cross-wind!

It is only 25kts when landing weather minima are predicated on autoland ops. Other times like day VMC it is the a/c limit which as I said is 38kts.

777 main gear and 747 body gear have no ability to do anything but stay inline with the longitudinal axis always.

I think he's referring to the text on the video, I would like to know what it says aswell.

Um, no.
The entire body gear on the 747 turn in the opposite direction to the nose gear, when on the ground.
I can't remember the figures off the top of my head but they start at about 10° nosewheel steering and move at about 10% as much as the nosewheel.
