Who'd worked building air planes a long time ago.

很久以前他就从事过制造飞机的工作。

Instead, he's devised a slightly more elaborate solution: building three identical planes for the mission.

相反， 他设计了一个稍微复杂的解决方案：为任务建造三架相同的飞机。

We were trying desperately to figure out what was going on. We were building the plane while it was flying up in the air and hoping we weren't crashing and burning.

我们拼命想弄清楚到底发生了什么。飞机在空中飞时我们希望自己不会坠机燃烧，但同时我们还是在继续造飞机。
