Endeavour on runway with Columbia on SCA overhead

The Space Shuttle Endeavour receives a high-flying salute from its sister Shuttle Columbia, atop NASA's Shuttle Carrier Aircraft, shortly after its landing 12 October 1994 at Edwards, California, to complete mission STS-68. Columbia was being ferried from the Kennedy Space Center, Florida to Air Force Plant 42, Palmdale, California, where it will undergo six months of inspections, modifications, and systems upgrades.
