Abstract: A thrusting rail-joint assembly for joining and rapidly separating two host structures is disclosed. Each of the two host structures may include a fairing structure, and is connected to a latching member, which may include a rail segment. An outer latching member, having a first joining end and a first latching end, is secured to the first host structure at the first joining end. The outer latching member includes a number of latching arms at the first latching end. The latching arms extend from the outer latching member in a direction from the first joining end to the first latching end. An inner latching member has a second joining end and a second latching end. The inner latching member is secured to the second host structure at the second joining end, and has a number of recesses at the second latching end. The recesses are adapted to receive the latching arms when the outer latching member is latched onto the inner latching member.
