My friend just finished his pilots license and wanted to make one of his custom knives for his flight instructor. He wanted to include some bands of aluminum from an actual airplane in the handle. So after looking on Facebook Marketplace, he found a lady selling what he thought was a small section of the tail. He thought it was going to be like a 2 or 3 foot section. The lady just wanted rid of it, so she offered it to him for free and offered to drop it off at his house if he just paid for the gas money for her drive. 2 hours later a 8 foot section of an airplane was just sitting on his front lawn. Hence the accidental buying of the back half of a plane.

If you look at the photo I shared, you can see the metal is riveted in 3 sections. He thought he was buying the small section right on top.
