I remember where I was for:
First moon landing (woken and got out of bed by my dad to watch on TV)
The Munich Olympics massacre (at home with parents, watching TV)
The first news report of the Ethipian famine ('a famine of biblical proportions'. About to have special tea with my mum - trout - which neither of us could then eat).
Seoul Olympics Ben Johnson doping scandal (watched on TV with kids at school and had to shift from 'how fabulous a runne' to 'what a cheat' overnight)
Apollo 13 (again, watched with kids. All the excitement of the build-up, then the tension)
Challenger shuttle explosion (as above, but with a worse outcome)
Diana's wedding ( with a friend. Diana was our age and we watched in disbelief at someone like us marrying into that)
York Minster fire (walking through London with a friend from York. We saw the newspaper billboard and silently went to buy a paper)
Diana's death (camping in Wales. The news flew round the campsite)
Heysell disaster (watching with my SIL, waiting for my brother to come out of a meeting)
Diana's funeral (again with my SIL, after the weirdest week ever)
9/11 and 7/7 (posted about on the other thread)
Yorkshire Ripper conviction (he was a large part of my university experience in a Yorkshire city)
So many, mostly traumatic events.
