We had a couple of very windy days over here in Europe.
Look at a crosswind landing of an A320 at HAM, a near crash:

Next time someone tries to tell you that airliners just "kick it
straight" when they land, like this guy did, show em this...
Watched the video and it looked like he tried to
kick it straight with the ailerons instead of the
rudder. *Am I missing something?
You can't generate much yaw with aileron. *The pilot did generate a
fair amount of left yaw (either using rudder or the left brake), which
(combined with the crosswind) gave him a nasty left roll. *It looked
like he applied a lot of right aileron before he drug the wingtip, but
it wasn't enough. *A boot full of right rudder at that point might
have kept him from dragging the wingtip, but that would have worsened
his already bad runway alignment problem.
That's it. here's a well known video full of x-wind landings. Some good ,
some bad.

Note the 747 at about 1:45 THat airplane has to land pretty much wings
level and the technique is well done here. There is some yaw introduced at
about 100 feet, probably as an adjustment for tracking rather than to
align. The lion's share is not eliminated until after touchdown and the
observer will notice a large amount of left aileron is simultaneously
introduced.
It can be seen that the touchdown is achieved with some drift going on,
which is just something that has to be lived with if you can't touch down
slipping. It works, but it's messy and to be avoided if possible.- Hide quoted text -

Do the 747s have crabbing gears?
