At that time I was working in the European HQ
of a major American corporation. Roughly the staff in that office numbered around 100 and comprised a quarter Brits assigned from the UK subsidiary, a quarter other Europeans assigned from other European subsidiaries, a quarter local directly employed staff (such as secretaries and house management) and a quarter assignees from the American parent corporation.
Of those Americans I worked with I knew that just one was staying in the UK for Christmas. Both his and his wife's families were visiting from the US. I knew that all the other American ex-pats were flying home with their immediate families for Christmas and the New Year.
It was with great trepidation that I travelled into London the morning after the PA103 atrocity. But we were very lucky. It transpired that none of my colleagues nor any of their families were travelling on the "Maid of the Seas".
Of course that was no recompense for the families who lost loved ones at the worst possible time. Sadly most of the 243 murdered passengers were travelling home to join their wider families for the holidays. And the 16 crew and 11 killed on the ground were equally innocent. RIP.
