How many of you old timers in SoCal know where this place is? It was once known as the Tustin Blimp Base and then later, the the El Toro Marine Corp Air Station. And in 1950, for about a year only, they held drag races there.
The structures themselves (there are two of them) are the largest wooden buildings ever built.
Shaped like two enormous pup tents and visible for miles, the giant twin hangars at the Tustin Marine Corps air base rise so high that clouds and fog form inside them. An architectural rarity, they stand as tall as an 18-story skyscraper and longer than three football fields.
Built in 1942 at a cost of $2 1/2 million each, they once housed helium-filled airships that cruised the coastline searching for enemy submarines during World War II. Because of the wartime shortage of steel, the hangars were built with alternate materials: They are the largest unsupported wooden structures in the world and can house six dirigibles each.
The base was decommissioned as a blimp base in 1949 and recommissioned two years later as the nation's first installation devoted to helicopters.
In 1987, the hangars were designated official National Historical Landmarks.
