I too am also amazed that they havn't grounded 777's. This must mean that they do know what happened!

I am
not amazed that they haven't grounded the type. Since this is the first hull loss of the type in ten years, whatever caused it is rare. Secondly, to ground the type would cause more loss of money than would be caused by a hull loss with all lives. That might be harsh but it is the kind of decision that insurers and public transport companies make every day.
