Delta Air Lines Flight 191
As the aircraft then begins to gain speed for no apparent reason, the captain warns the first officer, who is currently the pilot flying, to "watch your speed", and then says "you're going to lose it all of a sudden, there it is". The L-1011 then begins a rapid descent, and the captain then says "push it [the throttles], push it way up". The first officer replies, "way up", which is then replied to by the flight engineer saying "way up", and the captain then replies to this, also saying "way up", and then, "that's it", referring to the throttles being at their full forward stop. The engines begin to spool, and the aircraft continues to descend, losing speed, then gaining speed again.
