The Tustin Marine Corps Air Station was designated an Orange County Local Historical Civil Engineering Landmark in 1987 and designated a National Historical Civil Engineering Landmark in 1994.  The plaques were removed when the US Marines decommissioned the base.  The Orange County Branch rededicated the plaque in 2013 as part of our 60th anniversary.

The City of Tustin created a video of the history of the blimp hangars, including some footage of construction.
