From the OCFA PIO:
"Due to the dynamic nature of the fire, and the imminent danger of collapse, we have determined the most operationally sound method is to allow the structure to collapse, at which point ground crews can move in closer, and aggressively work to extinguish the fire."
This scene in the 2009 #StarTrek movie, where the two Spocks meet, was filmed in the Tustin blimp hangar.
The Tustin "Lighter Than Air" (LTA) hangars were built in 1942, originally for blimps to hunt Japanese submarines off the Southern California coast.
They were converted for use with Marine Corps helicopters. My wife's father worked there.
When the base closed in the 1990s, Tustin scrambled to find practical uses for them. One was converted to a film stage. The other was in too poor a condition.
In the fourth photo, I believe it's the rear hangar that burned today, not the film stage.

This KCAL-TV Channel 9 video is on the history of the Tustin blimp hangars.
From #OCRegister:
The fire is in one of two hangars that once housed blimps used in World War II and later provided cover for military helicopters.
The historic hangars have been featured in television and films, including โJAG, โ โThe X Files,โ โAustin Powers,โ โPearl Harbor โ and โStar Trek.โ
