American Airlines testing new airport screening device with US govt

American Airlines and the US TSA said Thursday they were testing a new high-definition airport screening device that could allow passengers to keep liquids and laptops in carry-on luggage during screening and potentially avoid new restrictions on in-cabin electronics. The new computer tomography or "CT" scanner is being tested in a pilot project in single checkpoint lane at Phoenix International and could be a long-term solution to avoiding additional security measures. Similar testing is expected to begin in Boston later this month, officials said. The technology is similar to what is currently used to inspect checked luggage at US airports today, but traditional X-ray machines are used to inspect carry-on luggage. <br/>
