It is a really small and decent museum worth visiting if you love airplanes. I wouldn't recommend it otherwise, although I must admit the people working there have put a great lot of effort into it. I especially liked the simulator that they have set up, which unfortunately was undergoing maintenace during my visit.
Nice militar museum in Lulea. The museum is not so big but it has really interesting historical pieces as well as a 6 or 7 war planes and a helicopter. There is also a flight simulator that seem really fun. The staff was really nice as they took the time to show me around in english.
