Härmälänranta mural

My father and mother were both working at the State Aircraft Factory. I also remember well those trolley buses from my childhood.
Härmälänranta's 47-meter mural is a work by the Hungarian artist Fat Heat.
VL Viima II – A Domestic Basic Trainer of the Finnish Air Force

The VL Viima biplane was designed at the Finnish State Aircraft Factory in the mid-1930’s, to replace the Czechoslovakian Letov Š 218 Smolik basic trainer.
The Viima, designed by a team of engineers led by Arvo Ylinen, flew its maiden flight in January 1936. The performance of the first prototype didn’t satisfy the Air Force, so the aircraft was re-designed. The renewed prototype, Viima II, was accepted, and the Finnish Air Force placed an order of 20 Viimas during summer 1938. The Viimas were delivered in late 1939, and were marked “VI”. In total, 24 Viimas were manufactured for the Finnish Air Force.
