Taken from a post on afn, re the downed aircraft.
Some interesting information on how BUK missile systems work:
"As reported earlier by RIA, the Russian Defense Ministry says it had intercepted the activity of a Ukrainian radar system on the day the Malaysian plane went down in eastern Ukraine, the ministry’s press service said Friday.
"Throughout the day on July 17, Russian means of radar surveillance intercepted the operation of the Buk-M1 battery’s Kupol radar station located in the region of the populated area of Styla [30 kilometers south of Donetsk]," the press service said in a statement.
“The technical capabilities of the Buk-M1 allow the exchange of data on air targets between batteries of one battalion. Thus, the launch of rockets could have also occurred from any of the batteries deployed in the populated area of Avdeevka [8 kilometers north of Donetsk] or from Gruzsko-Zoryanskoe [25 kilometers east of Donetsk],” the ministry said.................
..................And finally, as RT reported, the national governor of the Donetsk region, Pavel Gubarev, admitted that while the separatists indeed are in possession of one BUK missile unit, it is not operational, and even if it was, it would be unable to reach a height of over 30,000 feet without central radar guidance which the Donetsk region does not have, once again suggesting that a Surface to Air Missile, if indeed one was used, came from the Ukraine side. Surely it will be very easy for international monitors to validate this report."
