Bojinka II
A major terror plot has been disrupted in the UK. The plan was to blow up five to ten airliners above the Atlantic, on their way from Heathrow to the US. Airlines that were targeted: United, American, Continental. 21 people arrested - most of them Pakistanis - possibly up to fifty were involved. This could have been much bigger than 9/11.
Sounds like a remake of Operation Bojinka from 1995:

The aircraft would have blown up over the Pacific Ocean and the South China Sea almost simultaneously. If this plan worked, several thousand would have perished, and air travel would have been shut down worldwide for days, if not weeks. The U.S. government estimated the prospective death toll to be about 4,000 if the plot had been executed.
Cogito
Anyway I think it would be more efficient and human to only check people whose potential-terrorist-likeliness is higher than 80 %. That should not be too difficult and would have no influence on safety. I will not be more specific on the subject of which criteria have to be taken into consideration to determine someone's PTL-factor, as I do not want to say illegal things, to avoid that I would express forbidden opinions, since it is obvious that free speech is an ancient aberration with its origins in a pre-civilised era.
