Malaysian Air Flight 17 likely joins group of deadly shoot downs

      |If Malaysian Airlines Flight 17 was shot down, it won’t be the first time this sort of incident has occurred. In 1983, a Soviet fighter shot down Korean Airlines Flight 007 on its way from New York to Seoul. And in 1988, a missile fired from the USS Vincennes in the Persian Gulf brought down Iran Air Flight 665. Scott Pelley reports.
