The Hollsmidt 222 or HT-1 was a Danish light utility amateur aircraft.
Design and development[edit]
The plane was designed by engineer Harald Thyregod in 1958 and built by a farmer Arne Hollænder and Aksel Smidt at Hollænder's farm in Aarre. Therefore, it is known as HT-1 for Harald Thyregod or Hollsmidt for two builders. The idea was to create a light, cheap aircraft, fit to homebuilding, with two engines giving more safety. The engines themselves were converted Volkswagen car engines.
Operational history[edit]
The plane was first flown by Harald Thyregod on 24 April 1964. It was used by Arne Hollænder and received a registration OY-FAI. At the end of airworthiness (estimated at 300 hours), in 1978 it was donated to Denmark's "flying" Museum (Dansk Veteranflysamling).
