Eric. Did you ever get a copy? Robert recorded the 20/20 special off public TV back in the 80's. It is only about 06 minutes long, and uncertain if it is an edited version of what you are speaking about. (It looks like the same text as what Jon placed up here, but it is so fuzzy, I can't tell with 100% certainty.)In re-watching it, Robert and I felt it unusual that the British Government sent a telex to them while on scene, and advised the research team to stop, as IF there were munitions aboard, danger exists, but they didn't know of such a thing existing. It was the only time I saw a conspiracy theory, except the brief clip on the National Geographic special with John Light speaking about the huge hole blown in the side of the ship, that they (N.G.) were unable to locate.
If not, Come on over, and we'll watch it!
