Now they're saying it could be a something as boring and mundane as a pitot tube icing up.

Investigators are pursuing a theory that excessive air speed -- potentially spurred by ice building up on electronic speed sensors -- contributed to the ocean crash of an Air France Airbus A330 amid heavy storms Monday, according to two industry officials familiar with the details.
Investigators believe that the so-called pitot tubes may have iced up as the Air France plane with 228 people on board flew through a thunderstorm that could have included heavy rain and violent updrafts, the two industry officials said.
So called pitot tubes? Is there are different term for them on transport category aircraft or something?
But, combine the violent thunderstorms with pilots thinking they're flying a lot slower than they are and...I'll let people with a whole lot more time than me do the speculating.
