Unfortunately, I didn't have my RB on having only just got back in from work and my wife was monopolising her lap-top! At about 1958 - 2002 this evening a pair of aircraft probably half or a mile line astern, passed overhead at about 3-4,000' guestimate, from the quick glance I had of the rear of the second one, they were twin jet engined with high tailplane (like Learjets - they may even have been LJs......? but I don't think so) in military colours. They continued west, probably 5-10 miles out over Mounts Bay, then did a slow turn to port and returned east, to the south of The Lizard - did anyone monitor them - any info. would be appreciated.
