I learned to fly at KAGC back in the 70's and heard the same story of a P-38 crashing on final for 31.

KAGC,
The story of Allegheny County Airport began in June 1928, when county residents authorized a $1.5 million bond issue to acquire land for an airport.
At that time, Bettis Field, also known as Pittsburgh-McKeesport Airport and dedicated in 1926, was the area's air flight hub.
Located on the present grounds of the Bettis Atomic Power Laboratory in West Mifflin, it also served as the landing area for the early mail planes.
On Sept. 11, 1931, Allegheny County Airport opened.

KAGC & Bettis Field are only about a mile or so apart.
A little bit about Greater PIT,
Until the beginning of World War II, Moon Township, PA was mostly a rural agricultural area. It was too far from downtown Pittsburgh to be considered the "suburb" that it is today, although it was served solely by Pittsburgh media and state/federal services. In the early 1920s, John A. Bell of Carnegie purchased a number of small farms in Moon and established a major commercial dairy farm on his 1,900 acres (7.7 km2) of land. He was bought out by Mr. and Mrs. E.E. Reick and C.F. Nettrour, owners of the established "Reick's" Dairy, who doubled the number of cattle at the farm.
By 1940, the United States was becoming involved in World War II. The Works Progress Administration (WPA) identified that the Pittsburgh area needed a military airport to defend the industrial wealth of the area, and provide a training base and stop-over facility. The agricultural expanses of Moon Township were attractive to the early airport planners in the city. The WPA bought the Bell Farm and began construction of the runways.
In 1944, Allegheny County officials proposed to expand the military airport with the addition of a commercial passenger terminal in order to relieve the Allegheny County Airport, which was built in 1926 and whose capacity was quickly becoming insufficient to support the growing demand for air travel. Ground was broken on the new airport on July 18, 1946. The new terminal building would eventually cost $33 million to build and was built exclusively by Pittsburgh-area companies. The new airport, christened as Greater Pittsburgh Airport (renamed Greater Pittsburgh International Airport in 1972 upon the opening of the International Arrivals Building) opened on May 31, 1952. The first flight occurred on June 3, 1952. In its full year of operation in 1953, over 1.4 million passengers used the terminal. At that time, "Greater Pitt" was considered "modern" and spacious. In fact, the airport was the largest in the United States, second only to Idlewild Airport (now JFK Airport) in New York when it was completed 5 years later.
