Allen Airways Flying Museum

The Allen Airways Flying Museum is an aviation museum at Gillespie Field in El Cajon, California, preserving and showcasing flight history. The current Gillespie Field airport handout, updated November 2025, lists the museum at 2020 N. Marshall Avenue, identifies visitor access as by appointment only, and gives (619) 596-2020; it is not a drop-in museum with published daily hours. The museum’s official website currently displays an under-construction notice, so confirm an appointment and current access arrangements before travel.
