I remember these .... I was in Britain but the programmes were the same. It's true that 1975 was a really big deal at the time, with expectations raised entirely by the WTS.. I mean, did they think that we made it up ourselves? Of course not !
By the Summer of the year '75 we could see that a lot still had to happen and we thought that maybe the old system would go a bit over ( due to a glitch in the calculation) perhaps a few months or a year, but never did we think it would be decades past.....
As for living in the twenty-first century ? Come on.... "the world can never last that long! "
