All of the available evidence points to terrorists launching a 2-pronged “bracketing” attack on what they thought was an El-Al 747.
They likely used Stinger missles launched from 2 boats under the flight path, about 3-5 miles apart.
Shoot the missles, dump the evidence overboard, wash down the boat, ride back to port with the hundreds of other boats out that day.
OK, now you got me because I'm not aware of any witness accounts that say they saw two separate missiles. I won't go into the range limitations and the fact that Stingers use a heat-seeking warhead and the engines weren't hit, but I will ask how the terrorists could pick out an El-Al 747 from miles away?
