Telescoping secondary barrier system

A secondary barrier configured to extend across an opening within an interior of an aircraft with the opening formed between a ceiling, a floor, and opposing lateral side walls, the secondary barrier comprising:

• a secondary barrier gate movable between an extended position and a retracted position, the secondary barrier gate comprising:
• outer legs comprising a plurality of telescoping members, the outer legs comprising a top end and a bottom end, the outer legs configured to be positioned between the extended position with the telescoping members extended outward and the retracted position with the telescoping members nested together;
• crossmembers that extend between and are connected to the outer legs;
• mounts that connect the top ends of the outer legs to the ceiling of the aircraft, the mounts configured to pivotably position the secondary barrier gate between a deployed position and a stowed position;
• wherein in the extended position and in the deployed position, the outer legs extend along the height of the opening between the ceiling and the floor and the crossmembers are spaced apart along the height and extend across a width of the opening between the lateral side walls to block the opening;
• and
• wherein in the retracted position the stowed position, the outer telescoping members are nested together and the crossmembers are positioned together and the secondary barrier gate is positioned to enable persons to move through the opening.
