This is actually the 2nd production Tristar. This L-1011 suffered such severe fuselage damage during a decompression incident over the Pacific (HNL-LAX) on August 23, 1995 that it was written off. Ex N302EA.
Another great airline and colourscheme gone, it was a victim of the terrorist attacks of September 11, 2001. Midway never restarted operations after airspace was shut down, and ceased operations on September 12 (the last flights were on the morning of 9/11).
