Abstract: The security system has a control. The control is attached to an actuator for emergency crash landing purposes and a manual controller. The controller is attached to a plurality of tethers, each having a fork at its terminal end. The fork is attached to several types of security devices. When the control is actuated, tension on the tethers causes the forks to become dislodged from the mechanisms to which they attach. Once dislodged, the mechanism are disabled, allowing easy access through the cockpit door. In this manner, security of the cockpit is insured, yet will not inhibit the crew's safety in the event of an emergency.
