A couple of years ago i attended a lecture by Tony Blackman who i believe was BAe's chief test pilot at the time. He spoke about how the chaps at Woodford set about equipping the Nimrods with Sidewinder. Apparently after a photo of the armed MR2 'leaked' its way into the international press, the Argies decided they didn't fancy coming face to face with a large hemp coloured aircraft armed to the teeth.
