During an early voyage of the experimental Kalinin K-7, the aircraft crashed, killing fourteen passengers and forcing Stalin to scrap the project. But an artist has reimagined an alternate history where the Soviet flying fortress takes on Nazi flying saucers.

Aircraft designer KA Kalinin designed the K-7, a massive and extremely expensive prototype plane that briefly carried passengers during 1933. However, the plane crashed in November 1933, causing the project to be scrapped before more prototypes could be built. These images imagine a battle-ready version of a plane similar to Kalinin's K-7, with enough firepower to take down another non-existent vehicle: the Nazi flying saucer.
