Every year at the end of September I go to the E day show in Prague, and on the Friday before the show I will normally visit the Czech Air Force Museum at Kbley just outside Prague. Here is a guide in 3 parts
The first part includes a video guide on how to get there from the centre of Prague and then we start a tour of the museum.
This is one of my favourite museums in the world and I can not believe it is free to enter, open April to October.
