Reply #21: Somewhere on the INTERNET there are recordings from

the cockpits of airliners prior to crashes. (I don't know the URL, try goggle). In several of those, the voice recording of the flight director could be heard saying the words "pull up, pull up".

Slightly changing the subject;

A collision over Switzerland a couple of years ago between a Russian plane and a German plan occurred as the two neared each other, the collision avoidance system (CAS) clearly instructed them to "dive,dive"
but the controller told them to climb. (I might have that back wards)
As it turned out, the CAS was correct and the controller, who was talking on the phone at the time (about another problem), was wrong.
The planes collided killing all. In the U.S., the regulation states that the pilots are supposed to go with the CAS rather than the traffic controller.
