I learned and refined my crosswind technique on that runway, both 33 and 15, while based at EGBB in a variety of turboprops and jets. As you say, Tubby; when the wind is from the west, it can be very challenging, and that hump in the runway does not help.
These conditions did not look too bad, but I was not in the cockpit, so cannot say. What they did not appear to do on either landing attempt was to yaw the aircraft straight by pushing the rudder immediately before touching down?
Rudder failure maybe? Rudder limiter stuck? (Although if it were, then an into-wind runway should be sought out).
I have never flown the ATP, but in crosswinds on other turboprops, transferring from crab approach to wing down (crossed controls), approach at, say, 1nm can be helpful.
