Did not a US military C-130 fall foul of this?
09/02/58 US Air Force RC-130 Crew: 17
(6 killed, bodies returned to US custody; 11 unaccounted for, no remains)
This aircraft was apparently shot down by Soviet fighters 24 miles inside Soviet airspace in Soviet Armenia. At first the Soviets denied any knowledge of the incident; they later stated that the aircraft had simply "crashed." The remains of 6 crewmembers were returned to US custody on September 24, 1958. The Soviets denied any knowledge of the 11 other crew members on October 16, 1958. However, "The Soviet magazine Ogonyok, in a January 15, 1961 article reported that eleven personnel parachuted from the aircraft and were captured in the town of Yerevan... Subsequently Soviet authorities reported the magazine presented incorrect facts." It is possible that this aircraft was "meaconed" into Soviet airspace deliberately by false navigational signals broadcast by the Soviets.Crewmembers: The two lists below are inconsistent with other information available on the numbers of casualties mentioned above. All accounts agree that 11 crewmembers were unaccounted for and 6 remains returned to US custody. However, 13 names, not 11, are on the list of unaccounted for crewmembers for this aircraft presented in January 1992 to the Russian Government by the US Government. The four names listed below under the "known dead" category are those men who were listed in a Spetember 13, 1958, New York Times article containing the names of all 17 crewmembers, but who are not among the 13 in the January 1992 list. Presumably, therefore, two of them in the January 1992 list are actually among those whose remains were returned to US custody.

Reference other incidents on the USSR/Iranian. Border google “meaconing Iran” and you’ll find several cases.
I was a member on a CENTO exercise in Turkey in 1976 along with a couple of senior Iranian officers, I asked them if they ever had any problems with border incidents. “Not at all”, they replied, “the rules are very clear - if they cross the border we shoot them down, and if we cross the border they shoot us down”.
Any aircraft crossing the border not on a flight plan or squawking emergency and calling on 121.5 would not have got far in one piece.
