United States ferry pilots delivered aircraft to Ladd Army Airfield in Fairbanks, Alaska. There each aircraft was serviced by USAAF personnel in preparation for Soviet inspection. After Soviet inspectors accepted the aircraft, five regiments of ferry pilots conveyed aircraft from Fairbanks to Soviet pilot training facilities near Krasnoyarsk. Each regiment was assigned to a specific segment of the route to become familiar with navigation and weather within that segment. Single-seat Bell P-39 Airacobra and Bell P-63 Kingcobra fighters flew in groups with a pair of multi-engine North American B-25 Mitchell or Douglas A-20 Havoc bombers. The lead bomber navigated for the flight and the trailing bomber watched for stragglers. Bombers and Douglas C-47 Skytrains might fly independently, and C-47s transported ferry pilots east for new aircraft.[1]

Soviet First regiment pilots accepted the planes at Fairbanks and flew over the Bering Strait via St. Lawrence Island.
