Highland Restricted Area before the flow arrows had been thought of in the back seat of a Jaguar T2. Roll and bunt over a hill into the valley below and a Buccaneer flashed by left to right and very close!! I kept him in sight and informed my driver of his departing engine exhausts. "Never mind him, Buccs fly in formation, look for his mates" from the front seat followed by a "**** this" and a low level abort told me he had found his mate(s) i just didn't see them!
