So, if you over inflate the fuselage, it breaks?
Don’t do that!
“Problem” solved.
Next?

Something is starting to emerge here and it isn’t sounding good.

The pressurized fuselage is inflated to “many times” its normal operating pressure? I though fatigue testing was done to 150 percent of certification standards, which certainly isn’t many time the normal operating pressure. Or am I wrong, which is entirely possible? Is this a test done until the fuselage ruptures?

Looks like the article has been corrected. More correctly, I suspect what it was meant to say it was pressurized to the limit load many times, not many times the limit load.

It now seems that this wan’t “a pressurization test” at all. I occurred during a wing-bending test, as part of which the fuselage was normally pressurized. At 99 percent of maximum test wing bend, the fuselage suddenly depressurized because an aft door blew off. And “blew off” probably is an exaggeration, since at first nobody seemed to know what caused the depressurization, so I wasn’t as though the door came off like a cork out of a champagne bottle. It probably “failed,” I’m guessing as a result of fuselage distortion caused by the extreme wing bending.
