Yuri Gagarin going into space is my first memory of anything that made world news. I thought it was so exciting!
My next clear memory of anything momentous was JFK's assassination. I remember my Mum being really upset.
The one that's stuck in my head though is Aberfan, it was just after my ninth birthday, and some of those poor children were a similar age to me. My parents were very upset, and later terribly angry that something so awful had been so preventable, but the 'Powers That Be' had just not cared at all!
I still can't watch footage of Aberfan, without lots of tears, it just brings it all back so clearly
