They had diverted but TFN was very busy in those days, as it was the only airport and received a lot of charter traffic, including wide-bodies.
The dan-air plabe G_BDAN was inbound from Manchester. Those poor people, all holidaymakers looking forward to a couple of weeks sunshine. The crash seems to have got very little coverage, despite the loss of British life.
I find TFN a very eerie airport and its history makes one shudder!
