They seem in a bit of a hurry!
Not surprising. The Egyptians want to avoid another tourism scare, of course. I don't know why dying from terrorism is more frightening than dying from an accident, but it is.
The French have an agenda, too, since the plane that crashed was built by their competitor (Boeing). If the cause is ruled to be terrorism, Airbus and Boeing both lose orders, but if it's a defect in a Boeing plane, Airbus can gain from it.
Unless there's some independent oversight, this investigation may need to be investigated...
I am not an airline expert but seem to believe that it takes days, months, forever to identify cause of catastrophe.
How can terrorism be ruled out so quickly? Were the black boxes located?
Even with a mechanical failure, could sabotage be ruled out so quickly? Have the mechanics, airline crews been investigated, interviewed, cleared???
