On October 22, 1938, in the basement of the Voronezh NKVD, Konstantin Kalinin, a brilliant aircraft designer, a friend of Sikorsky, the creator of the K-1 serial passenger plane, the pre-war flagship of Aeroflot K-5 and many others, was killed by a shot in the back of the head. The father of the future aircraft designer in the Imperial Army retired from ordinary soldiers to officers, reached the rank of captain. Kalinin Jr. was born on December 29, 1889. He followed in his father's footsteps - graduated from the Odessa Military School with the rank of artillery officer. Soon the First World War began. By survivors of Russian pilots, besides - a big fan of technical innovations, Konstantin Elektovich asked about the transition to aviation. In 1916, he graduated from the Gochina School of Aviation, and the theoretical course at the St. Petersburg Polytechnic Institute, and was appointed a military pilot in the 26th Air Corps of the 9th Army of the Romanian Front. In one of the air battles he was crucified, in the second he managed to destroy the bridge over the Bistesta river with two bombs. In the 1920s and early 1930s, Kalanin was considered one of the most promising Soviet aircraft designers. His plane, made according to the aerodynamics program of the "Fearful Wing", created the basis for the supersonic aviation of the future. Sikorsky twice named aircraft designer Kalinin to America. He realized that such people are rare and valuable. But Kalinin did not go.
