On the crosswind, all aviation videos (other than those taken standing
on the centre line) appear to show massive drift angles.
What sort of crosswind would require 10 deg of crab on an a/c of this
size ?
Ahem...
for an aircraft of ANY size, a 10 degree crab is required by an 18 kt
crosswind, for every 100 kts of approach sppeed.
But approaching aircraft are photographed by telephoto lenses - which
greatly exaggerate visual crab angle.

Brian, you're not quite right, it's more nearly an inverse
relationship between crab angle and airspeed, angle increasing as air
speed decreases for a given crosswind. Think of the crab angle if you
flew a 100 kt pproach into a 100 kt xwind. You'd fly at 90 degrees to
the runway and have the shortest landing roll you can possibly have
and still have a useful airplane afterwards!
Of course, getting to your tie down would be a problem.
