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.[1][2]

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.[1]

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 20 ft (6.1 m) span, but this was quickly increased to 30 ft (9.1 m) with tip extensions and finally the aircraft received a new 40 ft (12.2 m) 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.[1]

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".[1]

Only one Quark was built and it was registered with the US Federal Aviation Administration in the Experimental - amateur-built category.[1][2]

Operational history

The aircraft logged about 300 hours in its 30 ft (9.1 m) wingspan version. The Quark was removed from the FAA registry on 13 August 2002 and the aircraft likely no longer exists.[1][2]

gollark: After several hours training on Google GPUs that they let random people use for some reason, the model generates grammatically correct but nonsensical sentences.
gollark: It's very easy because someone else already did basically all the work and I just had to write a script to dump my Discord data package into a CSV file with pings and DMs scrubbed out.
gollark: My evil plan to train a small GPT-2 model on my Discord messages has begun.
