BOEING 707 x 737-900
Tenho curiosidade de saber se o B737-900 seria um 707 com duas turbinas, sao quase do mesmo comprimento e algumas coisas sao iguais?sei que sao totalmente diferentes no sentido de modernismo mas seria um 707 bireator?me parece que o 707 é mais gordo...

A única semelhança exterior entre os dois modelos é a seção 41 (parte frontal da fuselagem, a partir da porta de pax) com basicamente o mesmo desenho (porém sem as eyebrows nas janelas do cockpit) e a largura externa da fuselagem que tem os tradicionais 3.76m da família narrow body da Boeing.
De resto, as dimensões e ângulos da corda média aerodinâmica, diedro e enflechamento das asas, a empenagem, os estabilizadores horizontais, motores e sistemas são bem diferentes.
Abraços,
