"On the pilot's family, it might be they aren't allowed to talk? "
that's been my assumption
but then-iirc, the copilot's family IS talking, a little. Also, a friend of the pilot has been talking, so its not like no one is talking about him.
My understanding is that both would be equally under suspicion etc.
I do understand that they just might not want to talk, and personally I hope its just that.
I also don't think that even if his wife had just left, that that provides much of anything to go on. I'd hate a situation where the pilot is blamed, because we don't know what else it could be and the poor guy had happened to have a godawful double whammy of a bad day.
