Omega Air operated a B707-320 into Casement, in connection with a TV advert for Citron cars (standing by to be corrected, memory fading) , the BX I think. Lots of complaints were phoned in as the neigbours were not used to aircraft this size at the Don. The rest of the advert was shot in France, with the car nailed to the roof. (the IAA were having non of that !)
