coming home from Canada in the winter would often result in frozen u/c.
Usually only one of the MLG legs would refuse to move and the procedure you describe would be resorted to. Lots of ways to get a reluctant u/c down but some would have been very time consuming.
I seem to recall that when operating in very cold snowy climes we had to check on the initial taxy that the wheels actually rotated and that they were not merely being dragged along the ice by the power of the engines.
Does anyone know the outcome of the SI into the wheels up landing of the 'K' at Brize ? Only curious as if it was not tech then I have my own theory how it could happen.
