Just happened to see the DH-125 F-BKMF Air Affaires thread. I was at the Nice show on June 3, 1966 and took a pic of this DH-125. This pic also shows Air Affaires personnel. On June 5, 1966 I happened to be on the beach at the end of the runway when it went overhead, exploded and plunged into the Med. I had to run for my camera and took a slightly belated pic of the sad event. This pic has been zoomed in using PhotoShop. I remember that the original pic taken showed a Viscount well ahead and traveling from left to right relative to the DH-125 and this likely precipitated the desire to make the sharp turn.
I have the above two pics digitized. However, I do not know how to put them on this thread.
