How come these aircraft are being intercepted down over the Channel, as opposed to north of Scotland as they used to be?
In the case of the 28th January English Channel mission they were. The footage released by the Russians is from the 28th January. FB is one of the QRA Typhoons from RAF Coningsby and noted by aircraft enthusiasts. In the footage you will see also see a 6 Squadron Typhoon from RAF Lossiemouth. These Bears were running down the west coast of Eire route.
