I'll never forget the show they did to try to prove/disprove the explosive decompression myth.
They used a hulk at the boneyard at Mojave Airport, sealed and pressurised the fuselage, and and then shot a bullet into it to see if it would explosively decompress. Of course it didn't, so they declared the myth busted.
What they failed to take into account was the outside pressure of the aircraft was equivalent to about 3000' ASL, the height of Mojave Airport, not >20K' where an explosive decompression would occur!
