Well, last time was 2001 when they accidentally shot down a passenger plane with 78 people onboard and denied it at first.
However, they do have BUKs and types of SAMs in the area, and had recently been complaining of Russian jets flying into Ukrainian territory.
Do you have a source for that, please?
Let's be clear about what you just described. It's not just one call, it's a total of three allegedly intercepted calls, and only with the three edited together do we arrive at that full description. Do we know that all three calls took place the same day, or do we choose to believe it? It's evidence, no doubt. But they could be taking responsibility for downing a military plane in one call, and then simply describing the MH17 crash in the other calls made on other days, for all we know right now.
Yeah, they shot a civilian plane down accidentally 13 years ago. When it flew through an area where military exercises were taking place.
This plane was leaving the area and in contact with Ukrainian air traffic control. It was also obviously not a military jet given it was a mahoosive passenger plane!
The type of planes rebels have been targeting lately are military transport planes...
Source is wikipedia/any site with operational capabilities of modern aircraft. Go google it.
The calls were time tagged one after the other on the same day, between the same people. Remove thy tinfoil hat.
