The advanced imaging technology technology units (AITs) wererolled out Friday at John F. Kennedy International Airport.
"These machines represent an important way to stay ahead of the ever-evolving threat that faces the aviation sector,” said Department of Homeland Security Secretary Janet Napolitano.
Napolitano says current TSA scans and X-rays only detect metal objects. But terrorists now have a more advanced arsenal, and these machines can find weapons other detectors cannot.
"The AIT is a material advance,” she said. “It improves our abilities to spot non-metal materials and helps our TSA officers keep commercial aviation safe.”
The machines send what are called “backscatter X-rays” that can see through your clothes. Then an agent at a different location looks at the scan showing a chalky, detailed – and naked – outline of each passenger from the front and back. Closer inspections will then be done if anything looks suspicious.
The majority of passengers who spoke with NY1 on Friday morning said the machines make them feel safer.
