It looks like contractor UNISYS has been overbilling the government for security system upgrades at our airports since 9/11.

Federal auditors say the prime contractor on a $1 billion technology contract to improve the nation's transportation security system overbilled taxpayers for as much as 171,000 hours' worth of labor and overtime by charging up to $131 an hour for employees who were paid less than half that amount.

which almost exactly explains this:

The project is costing more than double the anticipated amount per month,

DUH!

Now this has been going on for what, four years? And they find out now? Sounds like they need to take some of that money they have been throwing around on no-bid contracts and redirect it to the General Accounting Office.

And conservatives really think private contractors are cheaper than having the government do it?
