TRAPs are keychains/bag tags cut from aircraft skin and components that come with a laser etched or printed design. They are functional items and come with a full-color printed PVC luggage tag. 

This TRAP was cut from a T-37B Tweet and is blue painted aluminum. These are cut from aircraft 68-8019. A total of 1269 T-37s were produced with the Air Force retiring the aircraft in 2009. The type was also used to develop the A-37 Dragonfly – a light attack aircraft that saw combat during the Vietnam War.
