and also the multiple altitudes. did these erratic altitude changes seem to give credence to the theory of what might have happened to the flight and can you share what you know about that? >> whatréhx it does suggest, an obviously there's so much here that we don't know, that someone was actually flying the plane manually. and who was thatperson and why were they doing that? this sort of opens up all these questions in that area. but the other thing we've been told is that pings coming off the rolls royce engines from the plane show that it fell 40,000 feet in the span of a minute. when american officials were told this, they said this doesn't make any sense. they said they couldn't believe that it fell that fast in such a short period of time. such a large thing. so what's happened is that the american officials are looking at all this stuff, and they can't really make heads or tails of any of it.
