It was one of the most frightening moments since the Cuban missile crisis. In the early morning hours of January 25, 1995 a Russian radar crew spotted a fast-moving object above the Barents Sea at Russia's northern border. A missile they couldn't identify. The Russians have always viewed U.S. nuclear submarines as the greatest threat; a Trident missile launched from that area could reach Russia's mainland in 10 minutes. At the Russian radar station, the crew saw the missile suddenly separate into several sections just as the warheads of a Trident missile would. Their trajectory seemed to be carrying them towards Moscow. In Moscow, a signal went out to the nuclear briefcases which always accompany President Boris Yeltsin and top defense officials. Russia had established a deadline: they're supposed to detect an attack, assess it and reach a decision on retaliation within 10 minutes.
There were only 5 minutes left. Urgent radio contact was made with Russian submarine commanders. Orders were given to go into a state of combat readiness and the military issued orders to the Strategic Forces to prepare to possibly receive the next command, which would have been the launch order.
For 4 minutes, the Russian commanders waited for the order to launch. The Russian strategic plans permit launching Russian missiles before enemy missiles hit Russian territory. Eight minutes after the alarm was first sounded, the mysterious objects fell into the seas. The decision to launch a retaliatory nuclear strike was averted; the Russian forces stood down.
Hours later, the Russians learned that the unidentified object had been a scientific rocket launched from Norway to study the Northern lights. The Russian government had been notified weeks earlier the launch was coming, but no one told the radar crew.
