Bellingcat&#x27;s reporting takes for granted that a BUK was used based on a good amount of evidence there there were BUKs in the area and there was a missile fired from the ground. They didn&#x27;t and couldn&#x27;t prove that it was what hit and downed MH17, they didn&#x27;t have access to the physical evidence and flight recorder.<p>They seem to have done a lot of good work trying to track the launcher down and analysing the evidence that was available to them, though I haven&#x27;t been following their reporting. Without the physical evidence being analyzed the link between the BUK and the plane was strong but not confirmed.
