机场放置安检仪的讨论可谓如火如荼
Actually there's still quite a lot of talk,

至今这些讨论仍不绝于耳
but there was a lot of talk then about

但从那时开始人们就开始经常讨论
the placement of machines to search the luggage that goes onboard.

应该如何安置行李安检仪了
The hand luggage was being searched anyway,

随身行李自然要被检查
but to search luggage going into the cabins.

当然这里说的是要放到客舱内的行李
It was pointed out at the time, this has changed since,

911之后有人指出美国并没有
there weren't actually enough machines in the U.S., on the day after 9/11,

足够的安检仪来检查要放入客舱内的行李
to search every single bag that went into the hold.

这一状况现在有所改善了
You'd hear discussions of the following type.

有些“砖家”们在午夜热线中提到说
look there's no point trying to do this,

完全没有必要这么做的
