They say they found nothing. I've read some of Jack Cashill's articles on the subject. He goes into quite a lot of detail about what sort of missile was probably used.
I have no information on what sort of missile was used. I only have information that demonstrates some sort of missile was used.
Lets say Iran built a specialized missile launcher for sneak attacks and mounted it on a converted ship. At no time over the last twenty years has anyone suspected the use of such a weapon in any of the airliner crashes since.
The information I have says rogue elements of Iran's military. Iran disavowed any involvement. Of course the way Iran behaves, who can say what is true about whether this mission had official sanction?
Which is it, the Navy or the Iranians? What is your information on what type of missile was used? How was the attack carried out? If actually carrying out a attack is more unlikely than a accident, the missile theory doesn't hold up, ergo, a accidental becomes the best explanation.
