This vehicle permit pass was given out for the arrival of the space shuttle Endeavour. Built later than the other space shuttles, the Endeavor did not arrive at the Kennedy Space Center until May 1991. Vehicle passes, such as this one, allowed employees involved in the Space Shuttle Program, as well as the general public, to witness the arrival of Endeavour first hand.
It belonged to Dennis Jenkins, a consulting aerospace engineer for the Space Shuttle Program, and author of Space Shuttle: The History of the National Space Transportation System, a definitive book detailing the development and first 100 flights of the space shuttles.
Jenkins donated the permit to the National Air and Space Museum in September 2011.
