Something doesn't add up
Primary source of report is state TV
Heli at FL120?
Main rotor strike? Seems unlikely and who saw it?
A320 carries 200 pax?
No eye witness reports
FWIW:
Main Rotor is what sticks out furthest from any helicopter, all around the helicopter, with the exception of the tail section and tail rotor on most helicopters. Hence, MOST likely point of contact during a midair. (For tandems like Chinook, you are back to Main Rotor is what sticks out furthest from any helicopter, though the nitpickers will point to refueling probes on some helicopters sticking out a bit further).
Your "seem unlikely" looks to be based on ignorance. (Or, you are having some fun and I didn't catch the tone).
Here's my theory...
MX were pulling the A320 into the hangar, forgot to open the upper door and sliced the stab off. Then, a helicopter was shot down nearby. The rest is journalism.
While amusing ... ??
