The exhaust coming out of aircraft engines looks pretty dangerous, generating huge amounts of thrust and pushing back tons of hot air. This horizontal component of lift is called Induced Drag. Its called induced drag since it only exists as a consequence of lift. If youre generating lift, youre stuck with induced drag as well.

Winging It Aside from the aforementioned desire for a greater aspect ratio for reduced drag, the one-piece Gweduck wing was developed for minimal weight, ease of construction and benign handling. Keeping drag corralled was emphasized as the Gweduck mission is foremost long-distance cruising. Maintenance room is generally very good.
