Quite a long time ago a Lockheed JetStar (owned by Mobil Oil) was undergoing a hull pressure test, wherein the ultimate pressure reached 21psi, before failure.
The fuselage was quite a sight, and the aeroplane was sent back to Lockheed, where the wing was demated, and attached to a brand new fuselage.
A not inexpensive project, to say the least.
Lockheed paid, IIRC.
A tough 'ole bird, the JetStar...
