Delivery and display
First heading north for scenic flyovers of Sacramento and San Francisco, the 747 jumbo jet was scheduled to — and may still — land at Los Angeles International Airport (LAX) between 11:30 a.m. and noon PDT (2:30-3 p.m. EDT, or 1830-1900 GMT) Thursday (Sept. 20). Whenever it finally arrives, a ceremony at the airport will welcome the shuttle to L.A. before work gets underway to remove Endeavour from the SCA using large cranes.

Final flight
The shuttle-era’s final ferry flight will take Endeavour on a cross-country tour. In addition to performing low passes while flying over several NASA facilities, the carrier aircraft and its orbiter passenger will make planned stops in Houston and El Paso in Texas, and at Edwards Air Force Base in southern California before finally landing at Los Angeles International Airport (LAX) on Sept. 20.
The journey, and its pre-departure preparations, are subject to both weather and operational constraints and could be delayed or changed, NASA officials advised.
Once on the ground in Los Angeles and without a corresponding Mate-Demate Device at LAX, Endeavour will be hoisted off the SCA using two large cranes and positioned onto a modified NASA overland transporter. On Oct. 12, the shuttle will begin a two day road trip to the California Science Center, moving through the streets of Inglewood and L.A. on a 12-mile (19-kilometer) journey to its new home.
The California Science Center will open the new Samuel Oschin Space Shuttle Endeavour Display Pavilion on Oct. 30.
