Apparently, all is not lost.
They are going to depressurise the main landing gear and pump up the nose so that the thrust line points at the ground.
Then when full reheat is selected, a land rover (or adapted mini) can push them tail-first along the runway to de-ice it. . .
A bit like the old ones that required something big to push against the thrust of the old centrifugal engines out of meatboxes (God I was qualified on that).
