".................................. The doomed aircraft this time, in mid-1981, was a Canadair Limited CL-44 transport, registration number LV-JTN, one of two owned by an obscure Argentine cargo line named 'Transporte Areo Rio Platense. Earlier in 1981 the aircraft had ostensibly been chartered through intermediaries to fly cargo from Larnaca (Cyprus) to Teheran (Iran). The airliner, as it turned out, first picked up the cargo in Tel Aviv before flying it to neutral Cyprus and on to war-torn Iran. The cargo consisted of weapons for the war against Iraq.
Aboard the aircraft on the return leg to Cyprus were three Argentine crew niembers and a British citizen. Hector Cordero was the pilot; Jose Burgueno and Hermete Boasso were his crew. Stuart McCafferty was officially listed as "purser," but he was a representative of the brokers handling the arms sale. On July 18 the crew was making its third round trip.
The aircraft departed Teheran and headed northwest toward Turkish airspace. Because of intermittent air-to-air combat along the Iran-Iraq border, the airplane (like most others flying between Iran and points west) flew as far north as possible, skirting the southern Soviet border along the Caucasus Mountains.
There the crewmen made their mistake. Instead of following a heading of about 300 degrees to the Turkish. border and then turning left to a heading of 240 degrees direct to Cyprus, the aircraft seems to have been on a course about 5 degrees farther to the right, to the north. That took it over a section of Soviet Azerbaijan which juts southward along the generally southeast-northwest trend of the border. It flew parallel to the border, but on the Soviet side, for ten or twenty minutes.
By Soviet accounts released five years later, the "intruder" disregarded all radio calls (nobody at any Iranian or Turkish control tower seems to have heard such calls) and then ignored signals from escorting Soviet planes. That the Soviet military had botched the contact procedures seems much more likely, considering the level of skill (or lack of it) shown on other, similar occasions.
