The fuel is go, one point two g, cabin at 14 psi, oxygen is go!

燃料准备好了，1。2g，舱室压力为14psi，氧气准备好了" ！

Nuts and bolts, tire reinflated to 200 psi, hubcap back on, and the whole thing is gently lowered 5 centimeters back onto the ground.

、栓、将轮胎加压到两百磅，上轮毂盖，把整个轮胎缓慢厘米，返回地面。

The mechanics take off the hubcap and reduce the tire pressure from 200 to 30 psi, which reduces the risk of it exploding as the bolts and nuts holding it on the plane are removed.

机修工们取下轮毂盖，把轮胎压强从两百降到三十磅，这样当固定在飞机上的栓和被取下时，就可以降其爆炸的风险。
