Guam - Boosting the security measures by detecting both metal and non-metal items is the key reason for the airport implementing the new advance imagery technology scanners. Transportation Security Administration Federal Security Director Dan Astorga says they expect two of the new machines by spring on next year.

He says it would allow quicker access for passengers getting into the gate area, adding, "If a person wishes to opt out of the AIT unit, they can go through another process of screening, which may include the pat down procedure."

Controversy has surrounded the new system as travelers in the U.S. Mainland feel its too intrusive, but Astorga says its all part of ensuring no terroristic items make it into the airport and on the planes.
