NASA space shuttle hangar access tunnel covered in signatures goes on display

A short tunnel that once led into and out of NASA's space shuttle orbiters is now a portal for the public to see the many types of people who crossed that path.

The Pima Air and Space Museum in Tucson, Arizona now displays the crew module access (or white room) tunnel from Orbiter Processing Facility-2 (OPF-2) at the Kennedy Space Center in Florida. During its last few years of service, the tunnel's walls were signed by astronauts, engineers, technicians, members of the press and special guests as both an "I was here" and farewell testament to the space shuttle program.
