ボディアーマーを開発したのは何社ですか？
The British company Wilkinson Sword began to produce flak jackets for bomber crew in 1943 under contract with the Royal Air Force. It was realised that the majority of pilot deaths in the air was due to low velocity fragments rather than bullets. Surgeon of the United States Army Air Forces, Colonel M. C. Grow, stationed in Britain, thought that many wounds he was treating could have been prevented by some kind of light armor. Two types of armor were issued for different specifications. These jackets were made of nylon fabric and capable of stopping flak and shrapnel, but were not designed to stop bullets. Although they were considered too bulky for pilots using the Avro Lancaster bombers, they were adopted by United States Army Air Forces.
