It also features these space efficient tables located in the center of the aircraft. Wow.

还拥有位于飞机中心的高空间利用率的桌子。

I'm not going to get into too much detail about this for obvious reasons, but one of the most space efficient designs is a thermonuclear weapon; one that uses a fission reaction and then triggers a secondary fusion reaction.

出于明显的原因， 我不会对此进行过多的详细介绍，但最节省空间的设计之一是热核武器； 一种使用裂变反应然后触发二次聚变反应。
