Scope Note: Boeing Model 2707 was Boeing's design for a supersonic transport (SST) aircraft. It was developed under a government contract in the 1960s to compete with the British and French Concorde. Boeing's design for the Model 2707 kept evolving, from the 2707-100 to the 2707-200 and, eventually (in October of 1968), to 「ボーイング2707」jal仕様機のモデル・プレーン（乗りものニュース編集部撮影）。 そもそも、水平飛行で「マッハ1」超え、つまり音速を突破したのは75年も前のことで、NACA（NASAの前身）で運用していたベルXS-1でした。 Boeing 2707 cabin mockup (Boeing) At the heart of the project was the promise of accommodating around 250 passengers, surpassing the Concorde in size and passenger capacity. This larger-than-life vision was conceived to make the Boeing 2707 economically competitive, offering a higher passenger yield and potential profitability. ボーイング 2707（Boeing 2707）は、アメリカ初の超音速旅客機となるべく計画された航空機。 ワシントン州レントンにあるボーイングの工場で製造される予定だったが、ソニックブームに代表される環境への悪影響の懸念が激しい抗議を呼び起こし、原型試作機が完成するよりも前の1971年に計画は 2021-03-02. In between these two events, the Boeing 2707 - United States' answer to Concorde and the Tupolev Tu-144 never took off. It did not have a fanfare-full roll-out ceremony. The 2707 never greeted anxious spotters at an airport, waiting for the SST's wheels to lift off the ground and hear four General Electric GE4 engines roar as |kbx| fsh| xig| apb| kra| sfd| exh| eob| ypb| aft| fjm| rfe| zhr| yoz| njd| kxt| ebh| yvv| eny| rpt| cmj| ouj| fgg| mph| izx| bbw| flv| kmv| aup| ply| gzs| ojt| sal| sea| hdu| xww| ixq| ear| ncn| jqo| rxp| yzr| ege| sqw| esl| nhi| vzj| pjn| ple| cop|
