问题描述：
谁可以告诉我这里had not done
...A girl there told us the plane（ hadn’t come ）yet.In the end,there came an announcement telling us that the passengers waiting for Flight LJ108 could get a free meal and that the plane （hadn’t left ） London for some technical problems.
为什么这里用了两个had not done ,不是过去完成时吗?我不理解用这个时态
