Look's like your first reaction was right. However, I'm sure you would agree it would be foolhardy for any goverment to speculate on the cause of an aircraft coming down only to be proved wrong before the victims have been buried. Probably one of the quickest ways to loose worldwide credibility and look pretty stupid at the same time.My first reaction was that it had to be a bomb....... just surprised it took the 'experts' so long......... or rather so long to admit it........ politics
