If you ever get the opportunity to visit this museum I would recommend that you do. I was able to visit during one of the annual open days that they have in the summer. The RAF run buses from the main house to the museum during the open days. It is also open every Tuesday morning and on request according to the RAF website. The museum is in the middle of the RAF camp, and consists of a large building, and was opened in 1999 by a grandson of Lord Trenchard after whom the museum was named. The museum is centred around the history of the RAF at the Halton site, and covers the very beginning to the current date. There are many sections on the different sections, but much of it centres around the apprentice aspects of the camp. I quite liked the examples of tools made by the apprentices during their time at the camp. There is also plenty to see and do for young children in fact anyone interested in the RAF, Engineering and flight in general. If you are local you might find the old photo’s of the place particularly interesting. Some of the exhibits are interactive.
