Two airline baggage handlers used their employee uniforms and identification cards to carry a duffel bag loaded with guns and drugs into a plane's passenger cabin, bypassing security screeners, according to court documents. Passengers on the Delta flight from Florida to Puerto Rico were in little danger despite more than a dozen guns being on board, because at least two federal air marshals were also on the plane, a Transportation Security Administration spokesman said Thursday. TSA spokesman Christopher White declined to address the security breach or whether the marshals knew that guns were on the plane. He said multiple marshals were on the plane, but declined to specify how many. Thomas Anthony Munoz, 22, was arrested when he got off the plane in San Juan, while Zabdiel J. Santiago Balaguer, 22, was arrested late Tuesday and remained in custody Thursday in the Orange County Jail.
