A federal member of Parliament was warned about the Qantas incident, but he chose not to do anything about it.
Sheikh Haron has written letter to the CEO of Qantas stating that he had previously warned an Mp about these sorts of attacks, and says the jet was damaged deliberately.

Sheikh Haron has an announcement on his site saying that an attack will happen within a few weeks, and the date of the attack will be also announced in advance. I wonder what this is about? Has anyone else seen this?
