The final demise of Dan Air wasn't quite so clear cut as some would have us believe. I know one of the top people involved in trying to save Dan, they required six more weeks to restructure and keep a viable operation going.
The 'money men' would not give them that six weeks, it is rumoured, (this is PPRuNe), that pressure was put on the money men, from where? who knows, but if it originated with BA it certainly wouldn't be the first time they have used their contacts with government to engineer a decision to their liking.
BAs insurance cover renewal in 1983 immediately springs to mind.
