I hope everybody spotted the Sea Otter at the end of the film, hoping furiously to be mistaken for its older brother! Also what about the very strange fin flash on Walrus K5773, never seen anything like it. Remember that the finflash was removed from all RAF (and RN) aircraft in 1934, and were only reinstated during the fall of France. And it is pretty obvious why accidents during launching of these aircraft with catapults did occasionally go very wrong because somebody forgot to do something at the exact right moment - what a nightmare of a procedure. Makes operating contemporary landplanes look like a stroll in the park.
