9/11 is the one everyone alive at the time and old enough to does remember. I was home with dd who was just a baby at the time. Ex (then husband, army) phoned, told me to stay home, watch the news and he had no idea when he'd be home not to expect him that night certainly. He was right he didn't make it home till the following afternoon. As I got off the phone I saw footage of the 2nd plane hitting which had happened while he was on the phone to me. Ex is the least scaremongering type even with that job and he still warned me against using trains for the following few weeks and to keep my wits about me re suspicious packages etc. He knew I'd been an army brat during IRA years so knew the kinda thing to look out for.
Hillsborough - was dating a sports mad guy at the time and we were watching the match preamble on telly. I NEVER bought the "drunken fans causing trouble" bullshit cos I remembered seeing people helping kids get over the barriers and hearing shouts of "get help"
Chernobyl - happened at pretty much the height of the Cold War. Was genuinely frightened for nuclear fallout reaching us as nobody seemed to know at first what the risks were.
Zeebrugge ferry disaster - I lived somewhere that meant I was taking ferries myself quite regularly, awful.
Lockerbie - just horrific
Dunblane - also horrific and near some relatives.
Way too many child disappearances/deaths - and it's almost always somebody the child knows well & trusts, it's got the point now any male relatives they show in "appeals" I suspect (as apparently do the police)
Rachel McLean murder - I was living in Oxford at the time and felt something was off about where she'd supposedly gone from the beginning.
The Jill saward rape. The appallingly low sentences they got for the rape were shocking to me at the time - sadly I now know better.
Elizabeth fritzl - poor woman I can't imagine how you begin to recover from that! Jaycee dugard too.
Peter Tobin & similar - too often these people have already been convicted before of violent crimes. If Tobin had been serving a full life tariff for his rape conviction some of his victims could well still be alive.
The Berlin Wall coming down, my mum was in bits watching that news and through her tears trying to explain to me how awful it going up was.
Holly & Jessica - we (ex and I) were living near there at the time. I remember feeling nauseous as soon as Huntley was on telly even though at that time most people just thought he was s glory hunting twit! After Huntley was known to be at least a suspect I remember a journalist saying that she was among the press at that event where Huntley was pushing himself forward. She'd been a journalist a long time and it was the first time she felt she could not stand to touch a person and she'd dodged a handshake from him. She was saying she was so glad she did as she thought she'd have felt like scrubbing him off her if she had. Iirc she was also alluding to the fact that his confidence suggested this was not the first time he'd done this - I've always thought it strange that even with his "history" there seem to have been no investigations into whether he's implicated in other similar crimes in places he's lived that are unsolved.
Fred & rose west - again was living nearby at the time (dad and ex army moved around a lot). Angers me that within a few years after so many promises made that runaways wouldn't be ignored any more that this is exactly what happened.
Suzanne capper - ashamed to say that's the first I've heard of her. How the hell is it at all acceptable any of her attackers are free? Vile bastards!
I cried when Barack won the presidency, and I'm white! Seems ridiculous now but I really hoped it meant USA were becoming more enlightened and generally we tend to follow where they go. Sadly was a temporary situation apparently.
