Just the one sortie on XX699 - 5 May 96, 1.10, a De Havilland Trophy competition low level navex with a student from another UAS - I was the safety pilot. I guess the ac must have come from one of the other competing UASs as it was one of ours. I can't remember which one.
As I recall the stude took a bit of a wrong turning and tried to fly right over Grantham at low level.
