Two aircraft were ordered in 1940 August, and a third was ordered in December. A mockup was completed in the spring of 1941, and it first flew on September 21, 1942. Testing continued until February 18, 1943, when the second prototype crashed. Flown by Boeing's chief test pilot, Edmund T. "Eddie" Allen on a two-hour powerplant performance test, leaking fuel from a filler cap in the wing leading edge ran down inside the leading-edge and ignited, spreading to the engines. Due to the much reduced power, the aircraft, unable to climb, crashed into the Frye meat-packing plant, demolishing the majority of the packing plant and killing all eleven crew, 22 employees at the plant and one fireman.〔'Slaughterhouse Dive',Flypast Magazine June 2009 page 44 ISSN 0262-6950〕 The crash killed many élite Boeing personnel involved in the design; the pilot, Allen, was chief of the Research Division. After the crash, the United States Army Air Forces and a congressional committee headed by then-Senator Harry S. Truman investigated the B-29 program issuing a scathing report, prompting the Army Air Forces to take over the program. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Boeing B-29 Superfortress variants」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
