Terrorist plot to blow up planes mid flight.

I woke up hearing this on BBC Radio Five Live this morning. The plot involved using liquid explosives to bring down planes in the US, causing mass murder according to British Police. A quite sophsicated operation, as airports are geared upto dealing with solid explosives ie plastic explosives: BBC News Report CNN Report FoxNews Report Sky News Report This goes to show that the threat of Terrorism hasn't gone away. It's not if but when in regards to another Terrorist attack on the same sort of scale as 9/11 etc. Though this plot would have surpased 9/11 according to what i've caught on Skynews today (Fox news has been tapping into the sky news feed all morning).
