The first end of each strut being swingingly connected to the interior of the fuselage for swinging movement of the struts between a retracted position, wherein the struts do not obstruct the interior of the fuselage, and an extended position, wherein the struts extend substantially across the diameter of the interior of the fuselage. The movable tension tie assembly also includes first and second lock assemblies (14a) and (14b) rigidly connected to the interior of the fuselage for locking engagement with the struts.
