Bang and the Gas mask drop from the top, what to do??

Recently a BOEING 747 operated by Qantas Airline suffered a mid air explosion which torn away part of the right leading wing fillet. The airplane managed to land safely thanks to the pilot handling of the emergency and the inherent structural strength of the aircraft that prevent it from breaking apart.

Apparently a oxygen tank is missing after investigator inspect the gaping hole in the aircraft. Well the most important thing here to remember is not about the hole, missing oxygen tank or the explosion but the fact that every one is back on land safely.

So suppose (touch wood) you are flying on an airplane and the body of the plane suddenly got punctured. This will cause depressurizations of the cabin which means things will be suck out of the aircraft, living or non-living.

The first thing to do is to immediately fasten your seat belt. Hmm...didn't we always hear the inflight announcement to fasten the seat belt all the time but most of us don't besides landing and taking off times? Creature comfort I guess. Either you fasten seat belt all the time to in case of such contigency or you must posses quick hands before you get suck out of the aircraft, free falling to death.

The next thing is to don the oxygen mask that which right now should be hanging in front of you. It might sound heroic or brave to wear for the kid or old granny beside you first but most likely you will pass out after helping the kid. 5 minutes later, you will be brain dead if no one don the mask for you. At high altitude, air is thin and so is oxygen and a terrorized mind cause rapid heartbeat which consume more than the air could supply. ALWAYS WEAR THE MASK FOR YOURSELF BEFORE HELPING OTHERS WITH IT. Doing the other way round just give more trouble to the already chaotic flight cabin. Take care of yourself so you can take care of others.

If the oxygen mask fail to drop in front of you like what happen on certain passenger seats on this stricken Qantas plane. Hold you breath and share the oxygen mask with the person beside you.
