Security remains high at airports

Passengers throughout the United States are continuing to go through tightened security measures at airports following the Christmas Day bombing attempt of a US airliner.

First it was banning pocket knives and nail clippers. Then it was taking off your shoes. Then it was no liquids.

Now the government may want a closer look under your clothing.

On Wednesday, US Transportation Security Administration officials demonstrated two types of hyper-sensitive body scanners that create an image of a person's naked body on a security viewing screen.

The machines can detect metallic and non-metallic threats concealed underneath a person's clothing.

Some passengers have expressed displeasure with the increased surveillance.
