Thirty thousand feet above a roiling sea, two MiG-35s turned sharply to the south, their cockpits winking in the evening sun. As they began their descent towards the waves far below, both pilots knew that they were taking an unprecedented gamble, but they had been assured their presence would not attract the usual RAF escort. So far they had been left alone, apart from requests for identification from commercial air-traffic control on the ‘guard’ frequency, which they routinely ignored, a brief visit from two Norwegian F-16s, and a mid-air rendezvous with an Ilyushin IL-78 refuelling tanker.
At 1,500 feet they levelled out and took another, far graver risk. Within the next five seconds they would be entering Britain’s national air space, where they could be legitimately shot down. They set a course for Stornoway on the Isle of Lewis, twelve nautical miles away. Then, after wishing each other luck, both pilots hit their afterburners and accelerated to Mach 1.
In Alnwick, on the other side of the country, the Aerospace Battle Manager on duty at RAF Boulmer froze as he watched the two primary traces on his radar. The Russians were ten miles off the north-west coast, and closing. He had already rung through to Air Command at High Wycombe when the planes first entered the UK’s ADIZ, picked up by the radar head at Benbecula off North Uist, but his was a lone voice. The Russians weren’t showing up on Air Command’s real-time Recognised Air Picture for the sector. On his word, High Wycombe had brought two Typhoon crews at RAF Leuchars to cockpit readiness, but they were reluctant to scramble them until they had more concrete data.
‘The skies above the Outer Hebrides are showing clear,’ his opposite number had insisted.
Clear? He smacked the side of his radar screen in frustration. What the hell was going on? A terrorist strike? Two pilots trying to defect? It didn’t make any sense. He was used to long-range Russian bombers — most recently a TU160 Blackjack — keeping him busy on their eleven-hour flights around the Arctic. Usually, they would head for the North Pole and then hang a left just outside the Scandie’s ADIZ radar coverage and head down between Greenland and Iceland, skirting Britain’s ADIZ.
Both sides knew the game. The Russian pilots liked to test the range of Britain’s radars at Saxa Vord, Benbecula and Buchan, waiting for a response, which would often be intentionally delayed to confuse them. Moscow was also keen to measure the Quick Reaction Alert Force’s response, and the RAF was happy for the practice, shaving a few seconds off every time. There was no real animosity. (On one infamous occasion, an RAF pilot had held up a Page 3 girl in the cockpit, prompting his Russian counterpart to moon from a window of his bomber in response.)
But this time was different.
