decompression venting

 When the window blows out, get the air out as fast as you can

I've only ever seen it in films (thank g*d), but cabin decompression seems to take ages and people and stuff go out the hole with the air. Seems like a Bad Thing(tm).

I assume the compressors get switched off when there's a fast leak (same trigger as the mask drop?), but what about opening a larger hole in the opposite side of the cabin, but with a grille across it to stop the people going too?

Hafta say, I'd rather be cold and hugging an O2 mask than in freefall.

       Fixings are still rather tenuous, if you have a look.   

       Remember a United jet springing a leak over the Pacific about ten years ago? 11 people disappeared into the thin air of 40,000 feet before it got down to land. The roof section of about 40 feet of the 747 was also sinking slowly in the Pacific. Apparently it takes 8 minutes to fall that far...

       People and stuff departing prematurely through unauthorised exits is indeed a Bad Thing. At the back (usually) of the aircraft there are a number of big (think big pizza) sized valves letting the air out all the time. What happens when a shiney new hole appears, is these valves close up a bit, trying to keep the cabin pressurised. There is a switch in the pointy end which opens these valves fully, to ensure complete decompressurisation - used every time the aircraft lands. Landing with a pressurised cabin is also a Bad Thing, 'cos the doors won't open. Not sure about the grill - the pressure in the cabin would easily push you through it, so you would fall as chips.

       Why not just make people wear their seatbelts all the time to keep them selves from being sucked out of the airplane in case a big hole does appear in the wall.
