Boys and girls........What's done is done.
It makes no use or good by speculating or listening to media reports, especially when they interview passengers already suffering from shock for sensationalism.
There's always a "witness" prepared to get on camera and over dramatise actual events just to either get some cash or to get their 15 seconds of fame by seeing their rough melons on the screen.
We dont know the real facts or chain of events - that's why the Canadians have a very professional and experienced team to deal with it and investigate accordingly.
A well done to the crew though for dealing with whatever transpired by getting everyone off alive, I will say that much.
