New airport security rules mean travelers from 14 countries including Nigeria and Yemen will be subject to mandatory extra screening – including full-body pat-downs – before they can board a flight to the US.
Critics say that full-body scanners are costly, invasive, and will slow airport security further. The Puffer and the Guardian are alternatives, though not yet fully developed.
Full-body scanners could have foiled the Christmas Day airline bomb plot, some experts say. In 2010, US airports will add at least 150 to the 40 already in use, the TSA says. But critics say the machines won't help.

President Obama dramatically changed the tone of his administration's response to the Chirstmas Day attack on Northwest Flight 253, saying Tuesday that information about the alleged bomber 'was not effectively distributed.'
Senate confirmation of President Obama's nominee for head of the Transportation Security Administration was delayed by Republican Sen. Jim DeMint over unionization concerns. Experts say confirmation is urgent, but any blame for the attack on the agency is misplaced.
Airport security measures change in response to every plot, and the Christmas Day terrorist attack is no different. But use of screening technologies hasn't kept up with new terrorist methods.
Congress is gearing up to look into why the security changes made after 9/11 didn't prevent the failed Christmas Day terrorist attack on an airline landing in Detroit.
From 9/11 to the Christmas Day attack on Northwest Flight 253 over Detroit, terrorists have changed their tactics to get around airport security.
Airline passengers across Europe faced body searches and new limits on hand luggage. Authorities say that Umar Farouk Abdul Mutallab of Nigeria flew from Lagos to Amsterdam before boarding Northwest Airlines Flight 253 for Detroit.
