I seem to recall that it wasn't until after 9/11 that James Woods realized what he had witnessed and notified the FBI. The FBI had agents interviewing JW on 9/12-9/13 or so.
If memory serves.....
Yes, it wasn't till after 911, but it was right after that that he started speaking of it.
Someone somewhere on the thread said it was a year later that his story came out, but I know it wasn't that long after. It was right after.
