Web Watch: Liquid scanning machines

Posted: Updated:

The thought of traveling with a full-sized shampoo bottle brings many back to better times in the travel industry.

However, new technology may mean a return to 2005.

Liquid explosives are said to be the most serious threat to air travel safety. In 2006 security officials foiled a plot to send 10 liquid bombs on planes bound from the United Kingdom to the United States. Ever since then 3.4 fluid ounces is the limit for packing liquids in carry-on bags, but new technology could mean a change to those rules.

An Ohio-based company developed machines that use radio frequency and ultrasonic technology to scan liquids. The machines alert security personnel when something appears suspicious. All European airports are expected to have this technology by 2014. However, TSA officials in the U.S. say it is a long-term goal and is not ready just yet.
