I was at Malpensa on Wednesday, but didn't have time to go in, tho I will be going back there next year hopefully. I did have time tho to take a photo of a very nicely preserved Italian WWII single engine monoplane fighter parked outside the museum, in a very attractive desert camouflage scheme. I'll post it on Flickr and will then post a link to it here, once I've downloaded it from my camera.
