True. Not on the B707 or DC-8 (particularly not on the CFM-engined variants), and presumably not on the B747, A340 or A380. In fact, in my experience the nearest you can get to the sideslip technique on any big jet is the "wing-down" technique, which is normally done just before the flare/de-crab.

There are 2 runways at BHM; 06/24, and 18/36. Don't know which runway they were using, but there must be some good reason why an alternate runway, more into the wind, wasn't used, if indeed the winds would have been more favourable with the other runway. Maybe it was closed, who knows, anyone know what the reported wind actually was? Sam

BHX = Birmingham England UK. Which is where we are talking about.
A lot of these videos show crews not applying or relaxing, into wind aileron after touchdown, with a resulting struggle to maintain the centerline.
Q400 technique of crab, decrab at flare with associated into wind wing down, looks dramatic so is naturally a "star" for these videos.

Only half a speed-brake
My aircraft has dihedral on wings, once I neutralized into wing aileron after touchdown. Once in a lifetime moment, so no thank you.
Tendency to steer into the wind is normally attributed to the effect from vertical tail surfaces. The resulting wobble is more pronounced on high-wing aircraft or T/tails due their higher position of CoG over pivot point (wheels).

Nothing clever about those approaches. In particular one aircraft porpoising onto its nose wheel......Those Flybe crews were rolling the dice of fate.
Would be interested to know if the 500 foot gate and call to confirm a stabilised approach ( in the absence of which should be thrown away) still forms part of their SOP.....
