Stolen from Wikipedia:

The airport was originally named after daredevil aviator John Moisant, who died in an airplane crash on this land (which was devoted to farming at the time) in 1910. The abbreviation MSY was derived from Moisant Stock Yards, as the old airport kept NEW.

Plans for Moisant Field were begun in 1940, as New Orleans' older Shushan Airport – now New Orleans Lakefront Airport (NEW), still serving private and corporate aircraft – was in need of expansion or replacement. With World War II the land became a government air base. It was returned to civilian control after the war, and commercial service began at Moisant Field in May of 1946.

I wonder if there is any other field named after someone who died at that location?
