The attempt by a suicide bomber to blow up a US flight on Christmas day has resulted in a crack down in airports around the world. However it is starting to appear that computer systems are not up to the increased severity of patrolling such paranoia.

A company official says a United Airlines Express flight headed to Chicago had to return to St. Louis because of computer trouble in screening passengers. Spokesman Fred Oxley said GoJet Airlines, the regional carrier operating the flight, had a problem with its computers Friday morning, and manually checked in passengers.

However when the computers started to work again one of the passengers matched one on the Transportation Security Administration's “no fly” list. There was wide spread panic and the Airline ordered the flight to turn back. When it landed GoJet checked the passenger out and it turned out that they were not same person on the list. The plane took off again around 9:30 a.m. and landed in Chicago.

The TSA's no fly list has been criticised before because it is mostly a list of people that were not on George Bush's Christmas Card list rather than being a terrorist threat. However the computer systems that administer the list seem to be short on the sort of information that identify the people correctly.

If John Smith, 43, from New York, is identified as a terror suspect then ALL John Smith's who are 43, from New York will be questioned.
