That MiG pilot turned, leveled and fired a missile instead of launching it from flying steady and straight.
That vermin have good imagination: before that they claimed Russian airforce attacking their peaceful peasants with an anti-radar missile, like American HARM. They even showed the wreck of an unexploded (!!!) missile.
BTW it's a second Georgian drone lost over Abkhazia in 3 days. All this gimmicks are paid by American tax-payers, just in case you don't know. All Georgian govt gets it's salary in DoS, and it's a fact admitted by both sides. Their "armed forces" are also trained and armed by the US.
