USA — The TSA is working with American Airlines to bring about a new scanning machine that may change the experience of security lines for many travelers, reports CBS News.<br /><br />Travellers in the U.S. have become accustomed to long TSA lines where shoes and belts are removed, and smartphones are placed within X-ray machines, among other things.<br /><br />X-ray machines may soon be replaced with a CT, or computed tomography bag-scanning machine, which would create 3D images of the contents within a piece of luggage, reports Fortune.<br /><br />This way, passengers would not be required to take anything out of their carry-on baggage, as the machine would be able to "see through" it.<br /><br />TSA administrator David Pekoske described the technology as "revolutionary," reports CBS News.<br /><br />The machine would allow officers to directly zoom in and rotate the 3D image, which reportedly would be "much better at detection."<br /><br />Pekoske also said that in around five years, they expect passengers to not have to remove any items from their carry-on bags.
