Well, Estel, I was in the reconnaissance business from 74-80. I have never heard of a Soviet aircraft being shot down in International airspace by the USA.
I can't find any such incidents now using Google either, so I look forward to you providing incidents with dates that I might research.
I have found an incident or two like this:
“On February 27, 1974, a Soviet AN-24 reconnaissance aircraft was low on fuel and made an emergency landing at Gambell Airfield in Alaska. The crew remained on the aircraft overnight. They were provided space heaters and food. They were refueled the next day and they departed. The crew was not detained and the aircraft was not detained.
And there are an awful lot of incidents like this:
22 June 1955 A US Navy P2V-5 Neptune of VP-9 (BuNo 131515), flying a patrol mission from Kodiak Alaska, was attacked over the Bering Strait by two Soviet MiG-15 studmuffinots. The aircraft crash-landed on St. Lawrence Island after an engine was set afire. Of the eleven crew members, including pilot Richard F. Fischer, co-pilot David M. Lockhard, Donald E. Sonnek, Thaddeus Maziarz, Martin E. Berg, Eddie Benko, David Assard and Charles Shields, four sustained injuries due to gunfire and six were injured during the landing. The USA demanded $724,947 in compensation; the USSR finally paid half this amount.
July 1960 A US Air Force ERB-47H Stratojet (53-4281) of the 38th Strategic Reconnaissance Squadron, 55th Strategic Reconnaissance Wing, flying over the Barents Sea was downed by Soviet pilot Vasili Poliakov, flying a MiG-15 studmuffinot. Co-pilot Bruce Olmstead and navigator John McKone survived and were taken captive. The pilot, Bill Palm and ELINT operators Eugene Posa, Oscar Goforth and Dean Phillips were killed. Olmstead and McKone were released from Soviet captivity on January 25th, 1961. Bill Palm's remains were returned to the US on July 25, 1960. Eugene Posa's remains were recovered by the Soviets, but never returned to the US.
1967 A US Air Force ERB-47H Stratojet of the 55th Strategic Reconnaissance Wing, flying over Iran, near the Soviet border, was reported to have been hit by a Soviet surface-to-air missile. The damaged aircraft managed to reach the mountains north of Tehran, but crashed before being able to land, killing the entire crew.
And these are just three of many incidents.
So I look forward to your counterpoint.
