Le Bourget - Uboat Gyrocopter

Almost hidden in the rotary wing section of the museum was this 1 man gyrocopter. It was carried by German U Boats and used to get a lookout to a higher elevation. I wonder how effective it was and what the captain would do if he had to make a crash dive. I suspect the lookout would go swimming. Only 12 of these exist in museums around the world (2 in the US) and this museum is lucky to have one.
