Some of us remember when Hawkins & Powers, Hemet Valley Flying Service, SLAFCO, and others operated PBY air tankers. For those feeling nostalgic about the amphibious aircraft, the video below features a Consolidated PBY-5A that was found in South Africa and painstakingly restored.
Below is an example of another PBY, used as an air tanker.
UPDATE, December 4, 2014: Below is a photo I just ran across that I took around 1970-1972. It was most likely in California, and looks like Redding.
