No, he was not harassed. He said, he was sworn to secrecy but did not say if any reporter asked him anything. That was a different era where people kept their mouth shut if told to do so by superiors.
After I watch the show at sci-fi channel, I may be able to shed some light on it. But we will never know, the full story told by an eyewitness at that time, because, they did not understand what they saw. To them, it was plastic wires with light shining in them. Now we know, it must be fiber optics. It is very difficult to decipher any technology that is more advanced than ours at any given time period.
For example, remember the Indian link that talks about the Vimanas using Mercury as fuel. Well, we think, it is nonsense now. But what if they are say 50 years advanced than us where Mercury could be used as the fuel that creates an ion propulsion or particle beam drive to go to the moon. They also talk about the speed of the wind, it could be also a multiple speed of the wind (hypersonic)...Mahabharat talked about missiles turning corners to go after the target...now we have such weapons. They had stealth fighters, now we have them. They had visually stealth devices...we still are working on it.
