Krywlany airfield, Bialystok. This hangar was full of memories for me, Pirat SP-2876 was the glider that I flew in my very first gliding competition in my life, it was in 1976 from the Goclaw airfield in Warszawa. Soon after that Gaclaw was built over and become a subdistrict in Praga-Południe with a population of over 50.000 inhabitants.
