【SpaceX 和马斯克的可重复使用火箭是否受到麦克唐纳道格拉斯 DC-X 的启发？】
。
在 SpaceX 和 Blue Origin 等现代航天公司开始设计垂直发射和降落的火箭的二十年前，DC-X 就已经做到了。
。
由麦克唐纳道格拉斯制造的 DC-X 是 Delta Clipper Experimental 的缩写，是一种单级可重复使用火箭，旨在展示以前只能在科幻小说中实现的垂直起飞和垂直降落能力。事实上，DC-X 看起来就像是来自未来的。一个细长的白色金字塔，由四条细长的腿支撑。它只有 12 米高，在火箭中显得很矮小。
。
DC-X 的矮小身材证明这枚火箭从未打算达到轨道高度，而只是为了证明一个概念，一个航天工程师 Max Hunter 三十年来一直在培育的想法。亨特想要设计和建造一种单级入轨 (SSTO) 火箭，这种火箭无需消耗燃料箱、发动机和其他主要硬件即可进入轨道。本质上是一种可重复使用的火箭。

Twenty years before modern spaceflight companies like SpaceX and Blue Origin began designing rockets that launch and land vertically, the DC-X had already done it.
。
Manufactured by McDonnell Douglas, the DC-X, short for Delta Clipper Experimental, was a single stage reusable rocket that was conceived to demonstrate the vertical takeoff and vertical land capability that was previously only possible in the realms of science fiction. Indeed, the DC-X looked something straight from the future. An elongated, white pyramid standing on four slender legs. It was only 12 meters tall, a dwarf among rockets.
。
The DC-X’s small stature is evidence that the rocket was never meant to reach orbital altitudes, but only to prove a concept, an idea that aerospace engineer Max Hunter had been nurturing for thirty years. Hunter wanted to design and built a single-stage-to-orbit (SSTO) vehicle, one that reached orbit without expending fuel tanks, engines, and other major hardware. In essence, a reusable rocket.
