NEWARK, N.J. (AP) -- Security officials at Newark Liberty International Airport delayed a Las Vegas-bound flight Tuesday because a passenger was carrying two small knives in her luggage.
Continental Flight 768 missed its scheduled 7:30 a.m. departure.
Transportation Security Administration spokeswoman Ann Davis says a passenger looking through her overhead luggage had a small Swiss Army knife and another knife with a 2 1/2 inch blade.
Authorities declined to say if the bag's owner or someone else alerted the crew.
Davis says the plane returned to the gate and was cleared of passengers so a check could be conducted.
The passenger was questioned and released.
The TSA is investigating how the knives made it through security.
United Airlines Flight 93, which crashed in the 9/11 terrorist attacks, originated from Newark.
