There going to win the suit!. There was no reason for that chit to be dumped there. The tower even asked them if they had to dump, they said no and then dumped it. Lying to ATC will not go over well!
Pilots blew it big time and the company will pay out and a couple pilots are going to be looking for a new ride!
That plane was a "ocean crosser" and once airborne could fly OK with 1 engine. Those planes that go vast distances between land areas have to be 1 engine capable. They could have gotten height and then dumped it, it would then dissipate before it hit ground or ocean.
