What might rapid or explosive depressurization be caused by?

• A. Door leak allows slow air escape
• B. Window failure leading to rapid air loss and loud noise with no advance warning
• C. Engine failure
• D. Crew miscommunication

Answer: (B)

Rapid or explosive depressurization occurs when the cabin's air pressure seal is breached, allowing high-pressure cabin air to rush out rapidly. A window failure is a classic case because once the window fails, a breach is created immediately, and air escapes in a sudden, dramatic rush, producing a loud noise and little to no warning. In contrast, a door leak would let air escape slowly as the seal remains mostly intact, engine failure doesn’t inherently remove cabin air, and crew miscommunication has no direct mechanical effect on cabin pressure. Therefore, the window failure scenario best fits the description of rapid or explosive depressurization.
