I remember back in the late 70's when the US tried to rescue the hostages being held in Iran. The rescue Helicopters collided and crashed before the rescue. The buzz around the congregations in our area was that Watchtower prophecy was being fulfilled. They were quoting some pages out of some out-of-print Watchtower book which I can't remember the name of at this time. (your word is a lamp???...I can't remember if that was the book or not). I remember reading the pages and still couldn't make the connection.
But, it was proof enough that Armageddon was Right around the corner, and just seconds away on Jehovah's clock.
