Sovi­et pilot Chkalov crashed dur­ing a test flight on an I‑180 fight­er designed by Polikar­pov. The plane’s engine failed dur­ing land­ing. Try­ing to avoid falling on res­i­den­tial build­ings, the pilot col­lid­ed with a high-volt­age sup­port and died 2 hours lat­er in the Botkin hos­pi­tal. The urn with the ash­es of Valery Chkalov is locat­ed in the Krem­lin wall on Red Square in Moscow.
