A fascinating film. I had no idea that so many sailors were required to launch and recover aircraft! I also learned a plethora of nautical terms related to the lines and crane operations.
Mostly showing Walruses, but some interesting shots at the end of a wheeled Hawker Nimrod ditching, a Hawker Osprey (?) launching, where the occupant of the rear cockpit fell out and pictures of Sea Otters landing.
