SA-7's have been blamed for taking down several smaller airliners. Most recently, one struck a DHL A-300 taking off from Baghdad. The aircraft returned to the airport and landed. But Meyers accurately described the smoke trail of an SA-7 as being a corkscrew that remains long after the missile has hit its target. Furthermore, his discription of the descending arc of the streak of light he observed implies whatever he saw was flying a descending flightpath. SA-7's fly a pure pursuit flightpath directly toward their target. Not an up and over flightpath. The absence of a smoketrail and the flightpath discription Meyer's gives rules out the SA-7 as a source of TWA800's demise.
