There was also a similar line-up and pseudo paranoia in the 1980s - I want to say April or May1982, but I am not sure. I remember hearing about it as a kid. We used to have a section of the wall leading to the basement where we would write all sorts of things, growing up. My older brother and I wrote "Planets line up tomorrow, [date], world to end" or something... we didn't believe it, but thought it rather funny that people would believe something like that.
