Explosive decompression was a violent, unplanned drop in the pressure of a sealed system such as an aircraft cabin and typically resulted from human error, material fatigue, engineering failure or impact, causing a pressure vessel to vent into it's lower-pressure surroundings or fail to pressurize at all.

Explosive decompression was the means which Dr. Ryan Stone used to escape from the Soyuz Capsule so she could reach the Tiangong Station in Gravity.

Effects and DescriptionEdit

Explosive decompression occurred at a rate swifter than that at which air could escape from the lungs, typically in less than 0.1 to 0.5 seconds. After an explosive decompression within an aircraft, a heavy fog may immediately fill the interior as the relative humidity of cabin air rapidly changed as the air cooled and condensed. Military pilots with oxygen masks had to pressure-breathe where the lungs filled with air when relaxed and effort had to be exerted to expel the air again. The risk of lung trauma was very high as it was the danger from any unsecured objects that could become projectiles because of the explosive force which may be likened to a bomb detonation.
