I was 15 and saw it when I came in on the TV with my parents. I appreciated the enormity of it and well remember the tragic sight of his wife almost jumping out the back of the open car in shock and horror and then shielding his head and body.

I remember there was media speculation that he might not have died as news reported he'd gone to hospital and we awaited updates. I well recall my father saying of course he's dead. No-one could survive that.

We saw it as it happened because those were the days that we'd just got live broadcasting TV. So with big events like this families always sat down together to watch.

The next day we all had a minute's silence at school and our class wrote essays about the role of TV and other media in politics in our social and economic history class.
