And another idiotic theory,i was posted to RAF Laarbruch in the late 70s,on the nbc phase of the arrivals course this idiot(nice term) asks the course instructor if rabies has ever been considered as a biological weapon,cue scenes of incredulous laughter before the wing commander instructor composes himself and apologiseses(sp.?) by saying :the sight of buccaneers flying low level into soviet russia with alsations strapped to the pylons was just to much for me to take,cue scenes of more laughter with the person who originally asked the question unable to figure out what was so funny.
