MAN did make some questionable decisions last night, like refusing some but then accepting them too late. VS26, AA142 and CX38 are 3 examples that were initially refused but then accepted to the point of being on the MAN arrivals board, but it was too late.
However, it wasn't just MAN that got a slating last night, I have heard that despite its 21 diversions accepted, BHX did not come out smelling of roses either, so lets just draw a line under it, hope that lessons have been learnt for future issues and put it to bed. No amount of whining on here is going to change last night's outcome.
