1.   An emergency descent, for example, might be necessary if the plane lost cabin pressure and pilots needed to get to a lower altitude as fast as possible.

2.   Boeing officials suspect the air conditioning problem was responsible for the rapid loss of cabin pressure, but a cause still has not been determined.

3.   A NASA medical inquiry concluded that the force of the initial breakup was probably not fatal but that loss of cabin pressure may have been.

4.   Commercial airliners are equipped with audible cockpit warning alarms that will sound when the loss of cabin pressure exceeds pre-established limits, said FAA spokeswoman Kathleen Bergen.

5.   Ever heard about the inflatable bra that exploded on an airplane because of a sudden drop in cabin air pressure?

6.   Experts and government officials said the twin-engine jet, which took off from Orlando, Fla., probably lost cabin pressure, disabling and eventually killing those on board.

7.   Following the game, he boarded the flight home, which, Johnston recalled, was not a good idea, considering the changes in cabin pressure.

8.   If you go up in an airplane, as the cabin pressure drops, this can be spectacularly painful, as I well know from personal experience.

9.   It also made an emergency landing in Memphis a year ago when the plane lost cabin pressure.

10.   Like abruptly cutting cabin air pressure.
