What if the A320 had been on the ground and the Hip struck it whilst maneuvering too close - say - at night or otherwise?
The Syrian propaganda machine can't be trusted for the decent truth - anything threatening their public can be expected to be altered in the news.
The Hip wouldn't have TCAS but it has a transponder (IFF).
Regarding an earlier post here - the rebels dont have aircraft
If they tried to operate them, they would be blasted out of the sky in an instant.
Also, the rebels dont have SSR to pick up a transponder/IFF. At best they may have 57mm but in all likelihood its light AAA like 23mm or 14.5mm.
