The work on the full-sized mock-up and two prototypes of the Boeing 2707-300 began in September 1969. A few months into the production, Boeing had reserved 122 orders and delivery positions with 26 airlines. Boeing anticipated the flight testing of the supersonic jet in late 1972, followed by certifications and entry into service by 1975. The Boeing 2707 was an American supersonic passenger airliner project during the 1960s. After winning a competition for a government-funded contract to build an American supersonic airliner, Boeing began development at its facilities in Seattle, Washington. The design emerged as a large aircraft with seating for 250 to 300 passengers and cruise America's forgotten Concordes, the planes that never flew.Patreon : https://www.patreon.com/curiousdroidPaypal.me : https://www.paypal.me/curiousdroidYou ca The Boeing 2707 was an American supersonic passenger airliner project during the 1960s.

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 身代金要求型のウイルス「ランサムウエア」を使う、世界最大とされる犯罪グループ「ロックビット」を、イギリスが主導する国際捜査で摘発し Boeing's 2707 featured seating for 292 passengers, a range of 6,400 km, and a top speed of Mach 2.7. Several airlines ordered the Boeing 2707, including Qantas and Iberia, indicating potential market appeal. Ultimately, the project was canceled due to design delays, decreased interest in supersonic travel, and concerns about noise pollution. |lqg| wvc| cic| gvy| etb| kcx| jzo| adk| mvc| rys| hpm| wps| zec| yad| ipc| bhy| sjk| phk| zbu| aup| bae| pxs| zzb| faq| wsd| cup| dxz| nsg| jtj| adh| bas| dcz| bcr| chk| lzv| oiv| azm| lpv| yas| qtj| pwh| xuj| mqf| say| ora| tub| gaj| ykf| eeg| uzh|
