Castle Air Museum in Atwater hosted its annual fall Open Cockpit Day.
Visitors were allowed to climb inside 30 of the museum's 55 restored military aircraft.
The collection includes planes used in World War II, the Korean War and Vietnam.
A crew chief who's worked at the museum for 12 years says he loves sharing this history with guests, especially when it comes to World War II.
"I think it's one of the most important topics because the generation that came of age during the great depression and fought in World War II, what generation couldn't learn from them?" Castle Air Museum Crew Chief Kevin Garcia said.
The museum usually hosts open cockpit days to correspond with Labor Day and Memorial Day weekends but the grounds are open every day from 9 a.m. to 5 p.m.
