One deliberately ironic facet of the 2004 film Howard Hughes bio-pic The Aviator (the one with Leonardo DiCaprio) is the fact that the airlines fighting for world dominance in the 1940s were Howard Hughes’ TWA and Juan Trippe’s Pan Am.  By the time of the movie, of course, both famous airlines were gone.  Pan Am’s final descent into bankruptcy court ended in 1991.  Following its own troubles (and two bankruptcies in the 1990s), TWA was acquired by American Airlines in 2001.  But does the death of an airline mean an end to litigation?  Of course not.
