I remember it well. Everyone was convinced this was "it" (Armageddon). I started pioneering that summer, mainly due to peer pressure.
But I can honestly say, whenever talking to anyone about it, I always voiced my own personal reservations, based on Mt 24:44: " On this account YOU too prove yourselves ready, because at an hour that YOU do not think to be it, the Son of man is coming." To me, that everyone was SO expecting it simply proved that it was not to be.
Why was everyone so convinced? Not just by the various Watchtower and Kingdom Ministry articles. For many 'sensitive' subjects on which the Society don't want to commit themselves in print, they use the Circuit Overseers to stunning effect.
Whether at circuit assemblies, talks to congregations during circuit visits, or meetings with circuit or congregation elders, the Governing Body, and especially the Service Committee/Department, know they have a direct conduit to the sheep that totally bypasses the printing presses.
Back then, it was 1975, mini skirts, long hair (for men) and the evils of doing the twist! Nowadays, it's dealing with child abuse (to elders only) and "give us your money, we need another printing press."
They know they can say what they like and there's no official record, "nothing in writing" that can come back to haunt them in later years...
Neat, huh?
