在1960和1970年代，大部分个人和企业的飞机是飞行高度低于喷气式飞机的螺旋桨式或涡轮螺旋桨式飞机。

In the 1960s and 1970s, most personal and corporate planes were propeller or turbo-prop aircraft, which fly at a lower altitude than jetliners.

而且不同于喷气式战斗机，涡轮螺旋桨飞机可以在公路和田野上进行起飞与降落。

And, unlike jets, turboprops can use roads and fields for take-off and landing.

至少根据曾在20世纪70年代驾驶涡轮螺旋桨飞机完成在柬埔寨的战斗任务力德先生所言，涡轮螺旋桨飞机比起喷气式战斗机还有另一个好处。

And there is one other advantage that the turboprop has over the jet, at least according to Mr Read-who flew turboprops on combat missions in Cambodia during the 1970s.
