Got to come onboard on this one!
I am by trade an airframe engineer, punching a hole in the structure e.g. skin is not as big a problem as it seems, there will be at worst an "explosive decompression" this will lead to rapid pressure lost & loose items leaving the aircraft. The pressure drop will cause the release of the emergency oxygen masks, when tugged from their housings these will supply oxygen to the bearer ( note, put yours on first before trying to help your child! you will manage it with plenty of time to help others, if you try to help them first you may fail & them you are both done for! ) There will then be a "rapid descent" to 10,000 ft or below, you can breathe from there easily.
The real problem is serious structural damage, spar failure or similar, result curtains for all, explosion in fuel tank, you won't even know about it.
Hope none of us even try out the first option.
