While it has been touched on in a different thread, I believe this tragedy deserves its own thread.
Shortly after the Iranian missiles were launched at U.S. bases in Iraq, a Ukrainian airliner went down shortly after leaving Tehran. At the time, I conjectured that Iran had shot it down thinking it was an incoming American military plane in response to their missiles. Whether or not that was the case, it now seems that Iran did indeed shoot down the airliner, perhaps by mistake. Whatever happened is a true tragedy for all of those involved.
CNN Report with video that may show the actual shoot down. There are other sources available. I used this one because it seemed to be the most informative for now.
