This Invader became N9421Z in the early 1960s, and it was acquired in 1969 by Mr. Burchinall for display in his Flying Tigers Air Museum in Paris, TX. In January 1978 it was registered to Milt Stollak as N6240D, but apparently he donated it to the March Field Air Museum almost immediately, as it arrived there three months later. By 1982 it had been painted in black USAF markings with its original serial, later named "Sweet Miss Lillian", then by 2005 "Midnight Endeavour". By 2008 it had reverted to "Sweet Miss Lillian" again, as seen here.

Served postwar as N9421Z and N6240D before being preserved.
