In June of 2001 the DOD changed things at bit and CANCELLED CJCSI 3121.01A. How was it changed? Here....

a. Aircraft Piracy (Hijacking) of Civil and Military Aircraft. Pursuant to references a and b, the Administrator, Federal Aviation Administration (FAA), has exclusive responsibility to direct law enforcement activity related to actual or attempted aircraft piracy (hijacking) in the “special aircraft jurisdiction” of the United States. When requested by the Administrator, Department of Defense will provide assistance to these law enforcement efforts. Pursuant to reference c, the NMCC is the focal point within Department of Defense for providing assistance. In the event of a hijacking, the NMCC will be notified by the most expeditious means by the FAA. The NMCC will, with the exception of immediate responses as authorized by reference d, forward requests for DOD assistance to the Secretary of Defense for approval. DOD assistance to the FAA will be provided in accordance with reference d. Additional guidance is provided in Enclosure A.
