Airplane maker Boeing, major airlines and several airport operators, which face litigation from victims of the Sept. 11 terrorist attacks, sued the Federal Bureau of Investigation and the Central Intelligence Agency on Tuesday in a bid to question current and former FBI and CIA employees.

In separate lawsuits, the airlines and others are challenging decisions by the FBI and the CIA that prevent them from conducting depositions of those employees. The airlines include American Airlines, United Airlines, US Airways, Delta Air Lines, Continental Airlines and AirTran. The operators of Logan airport in Boston, and Ronald Reagan National and Dulles airports in Washington, D.C., also are plaintiffs.

The lawsuits, filed in federal court in Manhattan, are related to ongoing negligence litigation over the Sept. 11, 2001, attacks.

In the FBI lawsuit, the plaintiffs are seeking to conduct depositions of: Scott Billings, a FBI special agent formerly assigned to the Joint Terrorism Task Force; Erik T. Rigler, a former FBI special agent; Michael Rolince, a FBI section chief for International Terrorism Operations Section from 1998 to 2002; Coleen M. Rowley, a former FBI special agent and Minneapolis Chief Division Counsel; and Harry Samit, a FBI special agent assigned to the Minneapolis Field office and Joint Terrorism Task Force in August and September 2001. The agents were involved in FBI investigations of the terrorist organization al Qaeda and its operatives before and after the Sept. 11 attacks, according to the complaint.

In the CIA lawsuit, they are seeking to depose a former deputy chief of the CIA’s Osama Bin Laden unit code-named “John” and a FBI special agent assigned to that unit code-named “Mary.” They are believed to have information regarding two of the hijackers who carried out the attacks, according to the complaint.

Special Agent Richard Kolko, a FBI spokesman in Washington, said he wasn’t aware of the lawsuits and the FBI wouldn’t comment on ongoing litigation. A call to the CIA’s public-affairs office in Langley, Va., wasn’t immediately returned late Tuesday.
