BI-1 Monument in Yekaterinburg, Aviation monument in Koltsovo, Russia.

The BI-1 Monument is a white, full-size model of the BI-1 fighter mounted on a tilted pillar so that it appears to climb steeply, set on a stele on Bachchivandzhi Square by the parking area near Koltsovo Airport's main entrance. A memorial plaque beside it commemorates the aircraft and test pilot Grigory Bachchivandzhi; some accounts identify the model as a surviving BI-2.

The BI-1 was a liquid-fuel rocket fighter designed by A. Ya. Bereznyak, A. M. Isayev and V. F. Bolkhovitinov at a research institute on the site of today's Koltsovo airport. On 15 May 1942 test pilot Grigory Bakhchivandzhi made its first successful flight here. He died on 27 March 1943 when the BI-2 crashed during testing, and in 1962 the decision was taken to honour him and the aircraft; the monument was erected in April 1973.

Every 15 May, ceremonies at the monument mark the anniversary of the BI-1's successful test flight and honour its pilot, Grigory Bakhchivandzhi, who was posthumously named a Hero of the Soviet Union. A bust of Bakhchivandzhi also stands on the airport grounds.

The monument sits directly at the airport and is easy to view when arriving or departing. You can reach it from the terminal area without needing to enter the main airport building.

The white aircraft on the slanted pylon is a full-size model of the BI-1; some accounts say it is the surviving BI-2 airframe. The original BI-1 was a crewed cruise missile with a liquid-fuel rocket engine, and its development led to rocket engines later used in early Soviet missiles.
