I can't believe the idiots on here criticising the choice to return to LHR.
It was a successful and safe outcome. Just because you're closer to one airport when you're at 10000ft doesn't make it the best choice.
These pilots did a great job and I'm gobsmacked that posters claiming to be professional pilots are commenting when they weren't on the flight deck and they have no idea of the thought process that the pilots undertook. The aircraft landed, no one was injured and the aircraft will fly again. what more do you want?
