Lamson PL-1 Quark
The Lamson PL-1 Quark was an American high-wing, single-seat, glider that was designed and constructed by Philip Lamson, first flying in early 1965.
Design and development
Lamson designed and built the Quark in 1964 as a lighthearted experimental aircraft project to create a prone position-pilot glider. To this end the pilot was accommodated lying down with his head in the nose bubble.The PL-1 is constructed from fiberglass, with the wings made from a balsa-fiberglass sandwich that was laid up in a female mold. The wing was originally of span, but this was quickly increased to with tip extensions and finally the aircraft received a new three-piece wing. The airfoil was an Irv Culver modification to the NACA 0012. The landing gear was a monowheel, with small wing tip skids.
Soaring Magazine described the aircraft as "purely a lark and a quirky lark at that". The designer described the performance as "somewhere between a Nimbus and a Rogallo".
Only one Quark was built and it was registered with the US Federal Aviation Administration in the Experimental - amateur-built category.
