Most of the airplanes are rather old so can't be touched but there is an interactive section where little ones can sit in a helicopter or a glider. There are also lots of things to try out about physics that pilots need to know.
The museum was surprisingly empty so there were lots of chances to try everything out and have a go. Everybody's favourite was the beach ball that one had to balance over a stream of air and then shoot through a hoop. Little Monkey was too little to hold the air stream but he had a blast to fetch the beach ball.
