FT said "The former RAF officer, who flew fast jets, said that based on the evidence it would appear that the missile exploded in front and to the left of the aircraft.
Anti-aircraft missiles are not designed to score a direct hit as they are targeted to destroy fast, agile fighter jets. Instead, they are designed to explode within about 20m of their target, sending out a cloud of red hot metal to increase the chances of inflicting as much damage as possible.
The former RAF pilot said an explosion in front of the aircraft would be consistent with the interception course a SAM
So I should take the word of a pilot over that of a general who's in charge of anti-aircraft batallions? Makes sense. Unlike your final sentence.
Also, the pilot said "the missile exploded in front and to the left of the aircraft". Why, in that case, does the photograph you posted show holes indicating ingoing puncture marks. That means the explosion must have surrounded the aircraft.
Supplementary question: in the report redacted by the BBC but available elsewhere eyewitnesses stated they heard machine gun fir from overhead when they were asked if they heard/saw a missile. What is your reply to that?
As to why is Russia in Ukraine, I've already answered that but you keep ignoring it. According to the Separatist leader there are about 4000 foreigners fighting against Kiev, around 1000 of whom are Russian. OSCE has stated there is 'no mass build up of Russian troops' along the border with Ukraine. This has been backed up by UN observers and France24 journalists. I find it amusing that the US have satellite shots of the opposite but none of the shooting down of the airliner. Funny that.
