This PBY-5A Catalina was delivered to the US Navy with BuNo '2459', after its roll out 15 Nov 1941. It was responsible for sinking a few U-boats during WW2. This airframe is reputed to be the oldest airworthy example in the world. (scan from print)
Due to a seaplane meeting, this PBY made some "splash and go" on the lake of lucerne. Unfortunately the aircraft didn't came into the bay at the lucerne lido like the smaller aircraft did :-(
