Interesting article and story. I don't rightly recall ever hearing about this particular incident. I was 8; so I wonder if/when details were released to the public. You really wonder -- this would be a hugely dangerous incident and very embarrassing for the general public to find out about it, so you'd expect that the military would keep a lid on it, so to speak, for as long as possible. The cat was out of the bag by 1988, because a film was made about the incident, so it says.
