"I'll Be Around: B-17G, Pima, Arizona" - Daily Photo - 05/09/13
Had a request to include some narrative and any excuse to post a warplane and I'm on it!
Not a glamorous story according to Michael Benolkin at http://www.cybermodeler.com/special/restoration.shtml
"Our B-17 had an interesting life. It was a Lockheed-Vega-built B-17G that was delivered to the US Coast Guard for submarine hunting and air rescue duties. It had never seen combat in Europe or the Pacific. In place of the chin turret, our aircraft once had a radome to perform its search mission. Since the aircraft lived by the ocean, bare metal was out of the question.The Coast Guard applied coats of white paint to keep the corrosion under control. When the aircraft was retired from military service, she eventually found her way to dropping Borate on forest fires. Slurry tanks had been installed in the bomb bays. The fire fighting crews kept up the tradition of corrosion control – more white paint ... As we spoke to several of these crewmen, we discovered the fate of the original “I’ll Be Around”. The aircraft was enroute back to Framlingham after a combat mission and over the English Channel. One of the crewmen had removed the protective cover off of the very hotchin turret to safe the guns. Somehow a parachute dropped into the turret and caught fire.This in turn caused the 50 caliber rounds to start cooking off and the crew was forced to abandon the aircraft."
A radome (the word is a contraction of radar and dome) is a structural, weatherproof enclosure that protects a microwave (e.g. radar) antenna.
Assuming "Borate" is a component of fire suppression compounds.
