Re: The link.
Hmmm, I read it and must say:
I'm not impressed.
At all.
OK, nice collection of the AD's but in the text so much gets mixed up, is unprecisely described (e.g. mixing up QF72 and the Perpignan A320).
I would say: skip it.
There have been MUCH better scenarios and descriptions been done in this Forum / Thread.
