In Oct 87 I flew in the back of a Two Seater 104 (TF 2777) on a Taceval Chase Sortie out of Norvenich chasing 4 Tornados Lo Lo to 4 ATAF and back; we flew for 1.40 - I was a bit worried on the final approach in poorish viz when the Bingo light came on. (The chase pilot who was from Memmingham was not familiar with Norvenich!) It was a good sortie!
