Given the normal reaction on Pprune is,quite rightly, to support the pilots on board, I am quite surprised to see the hang 'em high brigade are out in force. They may well have made a mistake, but maybe the engine had another issue and maybe the other had a problem and thrust was reduced, so an immediate dump was appropriate. Let's wait for the detailed inquiry rather than feed the blood sucking lawyers that pervade US society.
I'm the long term I may be wrong in this case, but the first P in Pprune seems to be disappearing in favour of social media self glorification.
