Musculair 1 and Musculair 2 are two human-powered aircraft designed and built by German academic and engineer Günther Rochelt.
Musculair 1
Rochelt designed Musculair 1 and completed building it in 1984. His son, Holger, won a Kremer prize in the same year for his flight over a {{convert|1500|m|abbr=on}} triangular course, improving the record to 4 minutes and 25 seconds. In the same year, he set a world speed record at {{convert|35.7|km/h|abbr=on}}, receiving a second Kremer prize. Later that year, Holger and his sister Katrin, at that time still a child, became the first passengers in a human-powered aircraft.{{citation-needed|date=October 2022|reason=None of these claims are backed up by references}}

Musculair 2
Günther designed Musculair 2, and Holger slimmed down to just {{convert|41|kg}} to reduce the total mass of craft and human, leading to him setting a new Fédération Aéronautique Internationale world record for a human-powered aircraft at {{convert|44.32|km/h}} on 2 October 1985.{{cite web |date=2023-03-02 |title=Holger Rochelt (FRG) (389) |url=https://www.fai.org/record/389 |access-date=2020-12-04 |publisher=Fédération Aéronautique Internationale |language=en}} The record, which still stands as of 2023, was set over a circuit at the Sonderlandeplatz Oberschleißheim airfield, near Munich.
