About 200 Southwest Airlines pilots are testing new security devices at Baltimore-Washington International Airport designed to speed the screening process by getting airline personnel out out of the lines intended for the general public. "We felt TSA resources have been wasted on people who are not a security threat," said Capt. Carl Kuwitzky, the head of Southwest's pilots union. Rather than removing their shoes and belts with airline passengers, pilots can now use a separate line to prove their identity with a three-second thumb scan. Backers of the system say it can make airplanes safer while helping to relieve stress and congestion at security checkpoints.
