To do this requires a 360-degree view of the horizon and the astrodome was devised to allow an uninterrupted view of the sky from horizon to horizon. Astrodomes were prominent on many Royal Air Force (RAF) and Commonwealth operated multi-engined aircraft of the Second World War, and on foreign aircraft ordered by them for their use, such as the Liberator and Dakota, as a considerable part of the RAF's operations and other flying were carried out at night. ==References== 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「Astrodome (aeronautics)」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.
