pilot for a subsidiary of US Airways has pleaded guilty to selling a powder to help pilots and truck drivers beat drug test

pilot for a subsidiary of US Airways has pleaded guilty to selling a powder to help pilots and truck drivers beat drug tests.Stephen Sharp had a website where he claimed drug users could mix powder with juice one to five hours before a test and then just relax.He entered his plea Thursday at the federal courthouse in Pittsburgh. He works for a US Airways subsidiary called PSA Airlines. He has been removed from duty and is on unpaid leave."He guaranteed it was 100 percent effective and that it could be used to defeat any drug test," Robert Cessar, acting U.S. Attorney, said.Cessar says Sharp, of Port Orange, Fla., was selling a powdered drink mix from his website to help pilots, train engineers and truck drivers beat drug tests."If it's masking the substance that's the big concern - that would be similar to the horse racing industry where people do a thing called 'milkshaking' where they hide the drugs that are in the horse's system," Craig Conroy, an aviation expert from Gibsonia, said.The feds in Pittsburgh are cracking down on products designed to beat drug tests, recently going after the makers of the whizzinator, a prosthetic device also used to mask illegal drugs.

The U.S. attorney says there's no information at this time that Sharp was using drugs.

He'll return to Pittsburgh to be sentenced in September. He could get five years.

Prosecutors say the product did actually work.
