Newark, N.J. -- Baggage screeners at Newark Liberty International Airport spotted -- and then lost -- a fake bomb planted in luggage during a training exercise Tuesday night. The bag made it onto an Amsterdam-bound flight and was recovered when it landed.

Sens. Jon Corzine and Frank Lautenberg of New Jersey wrote to Transportation Security Administration chief David Stone on Wednesday, calling the fake bomb loss "alarming" and asking for an investigation.
