Was this another "Paddington' waiting to happen? Crews expressed concern about a problem in good time to stop it happening. Had rail crew not done exactly the same thing about the signal at Paddington? Was BALPA aware of the concerns? Were numerous D.Op's in the loop about their crews' concerns? It sure sounds like lots of people knew something was wrong, and yet it still happend. I thought aviation, in particular, had learnt all about being proactive in matters like this. It will be a fascinating AAIB report and the insurance loss adjusters will be taking aim shortly afterwards.
