Abstract: A frangible manifold is used in connection with flight termination operations and stage separation. The manifold has a first portion and a second portion separated by a frangible portion. An aperture extends through the first, second and third sections. A first ordnance termination line is positioned in at least the first section of the first portion of the manifold. A second ordnance termination line is positioned in at least the second section of the second portion of the manifold. In the event of a flight termination, detonation of one ordnance line causes detonation of the second ordnance line. In the event of stage separation, the manifold splits at the frangible portion and the two ordnance lines are safely separated.
