kaur---the UAV shoot down reports are manufactured KGB/FSB disinformation for several reasons;

The UAV named by the Russian private electronic warfare company Rostec indicated that it was a Hunter UAV which is a larger version of the Shadow which allows for great loiter time---using their own designation the following are questions they did not answer.

1. just what is a Russian private company doing working in the Crimea together with Russian troops
2. the range of the Hunter is 125 miles and even with a strong tail wind out of Bavaria where they claimed it was launched it would have not even come close to be over the Crimea
3. the US Army unit mentioned is based in Darmstadt and has no Hunters assigned to it
4. the Hunter could have been launched by a US Navy ship but there is only one destroy in the immediate area of the Crimea and it carries no Hunters
5. if this UAV is jammed as Rostec claimed and receives no ground signal it goes into a recovery loiter mode which is pre programed prior to start for another area other than what it is flying over then if jammed it goes into the recover to loiter area mode---if it then runs out of fuel during loiter mode a parachute deploys lowering it to the ground.

So all in all the story has no legs and is a blatant misinformation effort by the KGB/FSB.
