TIA to get upgraded scanner technology

Travelers soon won't need to worry about revealing too much skin during security scans at Tampa International Airport.

To blunt criticism that the fuzzy images of people's bodies amounted to a digital strip search, the Transportation Security Administration is installing software to make airport scanners across the country less intrusive.

With the older technology, travelers step inside a scanner that creates an X-ray-like image of their bodies beneath the outer layer of clothes. A TSA officer in a remote room examines the 3-D picture for suspicious items and passes along the results.

The upgraded machines produce a generic gray outline of a human form for every passenger on a screen attached to the scanning booth. Some workers have nicknamed the image "The Gumby." Potential weapons or explosives show up as yellow boxes located on the figure.

Screens, roughly the size of a laptop computer, flash a green "OK'' for passengers that pass the scan. Travelers who set off an alert will get a hands-on body search by a TSA officer. Ditto for passengers who refuse to submit to scanning.

The work to install the new software is under way at Tampa International, said TSA spokeswoman Sari Koshetz. Citing security concerns, she declined to say when machines with the new software will begin screening passengers at TIA's four gate terminals.

"We are installing it in Tampa and will do a demonstration for the traveling public soon,'' Koshetz said. Eventually, all scanners in U.S. airports that use radio waves to identify weapons hidden under clothes — called millimeter wave scanners — will get the software change.

The TSA tested the new software this year at Las Vegas McCarran International, Hartsfield-Jackson Atlanta International and Ronald Reagan Washington National airports.

"We believe it addresses the privacy issues that have been raised,'' said TSA Administrator John Pistole said at a Washington news conference in February.

The agency also found two other advantages: The upgraded machines take less time to screen travelers and don't require an officer to view the images in a remote room.

Pistole declared the tests a success three weeks ago and pledged to load the software into all of the TSA's 241 millimeter wave scanners — nearly half of all the scanners the agency operates.

L-3 Communications, a huge defense contractor headquartered in New York, assembles the ProVision millimeter wave machines in a plant just off Interstate 275 in St. Petersburg. The facility employs about 230 workers.

The TSA also buys scanners from Rapiscan Systems of Torrance, Calif., which uses X-rays to make a two-dimensional image for screening. Rapiscan is expected to have similar software that creates a generic passenger image ready for the TSA to start testing in the fall.

    Transportation

    TAMPA — For many, Wednesday's regional transportation meeting was a dose of deja vu.

    The Florida Department of Transportation on Monday announced that it was renaming its controversial Tampa Bay Express plan, also known as TBX. The plan will now be known as Tampa Bay Next, or TBN. But the plan remains the same: spend $60 billion to add 90 miles of toll roads to bay area interstates that are currently free of tolls.

  4. To catch a poacher: Florida wildlife officers set up undercover gator farm sting

    Wildlife

    To catch a ring of poachers who targeted Florida's million-dollar alligator farming industry, state wildlife officers created the ultimate undercover operation.

    To catch a ring of poachers who targeted Florida's million-dollar alligator farming industry, the Florida Fish and Wildlife Conservation Commission set up an undercover operation. They created their own alligator farm, complete with plenty of real, live alligators, watched over by real, live undercover wildlife officers. It also had hidden video cameras to record everything that happened. That was two years ago, and on Wednesday wildlife officers announced that they arrested nine people on  44 felony charges alleging they broke wildlife laws governing alligator harvesting, transporting eggs and hatchlings across state lines, dealing in stolen property, falsifying records, racketeering and conspiracy. The wildlife commission released these photos of alligators, eggs and hatchlings taken during the undercover operation. [Courtesy of Florida Fish and Wildlife Conservation Commission]
  5. CBO analysis: 23 million would lose health coverage under House-passed bill

    National

    WASHINGTON — The Republican health care bill that passed the House earlier this month would nearly double the number of Americans without health insurance over the next decade, according to a new analysis by the nonpartisan Congressional Budget Office.

    Demonstrators protests the passage of a House Republican health care bill, outside the the Capitol in Washington, on May 4. The House took the unusual step of voting on the American Health Care Act before the Congressional Budget Office could assess it. That analysis was released Thursday and it showed the bill would cause 23 million fewer people to have health insurance by 2026. Many additional consumers would see skimpier health coverage and higher deductibles, the budget office projected.
