I went to Imperial war museum Duxford to see the battle of britain air show.
I saw a lot of WW air planes and red arrows, these are quite interesting.
I quite liked old air plane graphics. It was a good experience I could go into some airplane's inside. It is quite amazing how our technology is changed in 50 or 70 years... I saw a lot of old GPS system there, these are quite simple, but I guess skilled people can operate these media, but now everyone has GPS our phone,,,
I put more photos on my flickr
