D/FW AIRPORT -- Passenger reaction ranged from indifference to intense dislike Friday morning as the Transportation Security Administration officially began using its "whole body imaging" machines at Terminal D.
The two millimeter-wave machines, which use electromagnetic waves to see through clothes and generate computer images of passengers' skin, are designed to detect hidden objects but have also raised concerns from civil rights advocates about possible privacy violations.
"There's nothing threatening about the machine -- you walk in, you walk out," said Diego Lemos, who was traveling from Miami to Minneapolis.
Brittanie Conklin, who was traveling home to the Kansas City, Mo., area after a vacation in Cancun, Mexico, called the experience awkward.
"It feels like all the attention's on you," she said.
Her brother Ethan, however, didn't like the experience at all.
"I don't like it. I don't really want people to see me," he said. "It shows your whole body. It's an invasion of your privacy."
The millimeter-wave machines, at the D18 and D22 checkpoints, are used randomly.
