Nine seconds later, the aircraft suddenly entered a steep dive. At 11:14:35, after 26 seconds of uncontrolled descent, the aircraft clipped a tree with its right wing and impacted the ice-covered moat of a 19th-century military fortress at a speed of approximately at a 20-degree down angle, away from the runway threshold and from a residential area. At the last moment Captain Lipowczan, using nothing but the plane's ailerons, managed to avoid hitting a correctional facility for teenagers located at Rozwojowa Street. On impact, the aircraft disintegrated; a large part of the main hull submerged in the moat, while the tail and parts of the main landing gear landed a few meters further, just before the entrance to the fort. On the scene, a diving team was later trying to recover parts of the aircraft (including some of the engines) from the moat, but it was far too murky; ultimately, the moat had to be drained to allow the air crash investigation team to recover parts of the disintegrated plane. The body of Captain Lipowczan was found lying on the street about from the crash site; other bodies were scattered between the plane parts.
