The Transportation Security Administration may screen your carry on bags with their new 3D X-Ray machines to spot liquid bombs, guns and other explosives.

The TSA has already limited the amount of liquids that passengers carry on board.

The main question lurking TSAs mind is whether to buy upgraded machines for $75,000 to $200,000 each or to wait for two more years for much advanced machines that would cost them $400,000 each. Presently TSA has planned to wait for the more advanced machines to arrive. These machines provide more detailed images of the scanned surfaces than the devices which have protected the air for around 30 years.

The new X-Ray machines are almost of the same size as the machines used at the U.S. airports. The machine is so fast that it can replace two X-Ray machines and will still save money as the number of screeners will be reduced. An automated Cobra sounds an alarm when it finds anything suspicious rather than requiring a screener to spot them on the X-Ray screen.
