What causes explosive decompression?
Explosive decompression happens when something causes the cabin to rapidly lose its pressure. This may be because of a failure in the structure of the plane or a collision with an external object. Air is constantly trying to push out of this high-pressure environment into the lower pressure of the exterior.

What are the signs of slow decompression?
One of the first physiological indications of a slow decompression may be ear discomfort or ‘popping’, joint pain, or stomach pain due to gas expansion. As mentioned, the greatest danger during decompression is hypoxia.
Why are bubbles bad for divers?
But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage. In extreme cases, it can cause paralysis or death if the bubbles are in the brain.
