N911NA: NASA's Second Shuttle Carrier

The second Shuttle Carrier Aircraft began as a Japan Air Lines short-range 747. NASA added it to reduce dependence on a single carrier. Despite its domestic-airliner origins, its converted performance matched NASA 905.

What makes this aircraft important

The former JAL registration was JA8117, not JA8817. Acquisition, registration changes and delivery after conversion are distinct milestones; the completed shuttle carrier did not arrive in 1988.

Status and access

The official collection or venue record lists this aircraft at Joe Davies Heritage Airpark, Palmdale. Interior access, tours and opening arrangements can change. Check the venue information before visiting.
