as soon as+过去完成,看不懂,
While we were waiting to land,a flight attendant told us to keep calm and to get off the plane quietly as soon as it had touched down.
我的问题在as soon as 后面+过去完成.
平时as soon as 的结构都是'主将从现',这里却是主句过去从句过去完成?
请问应该怎么把他看懂?

as soon as 的结构不一定是"主将从现"
主句如果是过去时,从句也要用过去时
没有什么主句要比从句晚一个时态的规律
如:
I arranged the flowers in the vase as soon as I came back home.
一回到家里,我就把花在花瓶里插好.
根据语境,这里用完成时,表示动作的完成( it had touched down飞机已经着陆)
整段话都是描述在过去发生的事,所以从句用过去完成时.
