A ridiculously extreme over-reaction from the Turks - they deserve whatever is coming to them when Vladimir Putin decides on the appropriate response.
Erdoğan isn't likely to find many people supporting such a stupid, disproportionate response to a 17 second incursion; perhaps he's trying to prove himself following the recent Turkish General Election?
Meanwhile, after admitting that his rebels murdered the Russian crew in their parachutes, Alpaslan Çelik's days are probably numbered, given that there are large numbers of Spetsnaz in Syria. Not people to be messed with - as he and his cohorts will probably discover to their cost.
