Norwegian rocket incident

In 1995, a team of American and Norwegian scientists fired a four-stage rocket into the sky to study the effects of the Aurora Borealis. At its peak height, the rocket resembled a U.S Navy Trident missile. Fearing that the U.S had just launched a surprise nuclear attack on them, Russia had nukes ready to fire, but one single man in the Russian security department decided that it wouldn't make sense for the U.S to do a surprise nuke attack, and ordered to not go through with the retaliation.
