The Pan American Boeing 707 Airplane Window ($1,500) is a cool historical gift for pilots, airplane aficionados, world travelers and more. This real window panel was actually part of the last existing Pan American Boeing 707, the N880PA. It includes all the necessary mounting hardware and instructions, so you can hang it on the wall in your den or home. It's certainly something different and I'm sure there are nostalgic collectors out there. It's kind of like when people buy pricey seating from demolished sports stadiums, which I don't understand either. (via Michael Kiely)
