EXPLOSIVE DECOMPRESSION

With the use of pressurized compartments there is a possibility of explosive decompression. This is most likely to occur if a blister is blown either due to gunfire or a defective blister. Due to the excess capacity of the superchargers, small cabin holes will not cause explosive decompression. If explosive decompression occurred at 30,000 ft, the pressure altitude of the cabins would change from 8,000 ft to 30,000 ft in less than one second. What would happen in such a case?
