If the radars were operable and properly manned. At the point they lost contact, they would have only been read by longer range type radar, which may not see a primary blip at that distance. (would be primary if transponder switched off)
Closer in the radar is a bit better and probably would set off some alerts.
Your mention of a lot of different people not wanting to share info is undoubtedly correct. I perceive a big "turf" war there, and the left hand will not let the right hand have any information.
Food for thought. There are a lot of training scenarios going on in that region where fighters intercept airliners for practice.
A few years ago, an F-4 hit a Spanish DC-9 and everyone but the F-4 RIO died.
Not saying this is the case, but someone there knows more than what is being published.
