Same system which shot down USAF F-16 pilot O'Grady over Bosnia (while at a very high altitude).
Complication: How would you spirit one of these across a border..?
The report said ROCKET, and most rockets are not guided. So a near-miss would suggest the a/c was flying at a VERY low altitude at the time of this alleged miss.
But the complication to THAT is that 90% of journalists use errant words when reporting about weapons matters --we don't REALLY know what the journalist was told.
ANYTHING to a journo is a Glock or AK-47....
The Russian RPG’s have been used to take down helicopters. I would not be surprised if a rag fired an RPG-29 at an approaching aircraft. They have a range up to 2600 feet.
They are/were in the inventory of Libya, Syria, Hamas, and Pakistan.
Hitting an aircraft at speed would be just Sierra Hotel Lima.
