Aliens?
#13
yes, they have. Russian navy was doing subsurface test launch of their still in development missile called "bulava" ([boo-la-vah]). The launch went fine at first, but the 3- rd stage malfunctioned and started spinning the tail, hence the spiral pattern. The light show was so vivid because they usually launch the missile from the border with Norway and in the general direction of Alaska which gives them the full test range close to 10K km. Usually the test missiles fly into the window of the abandoned house at Kurah test grounds and explode ;-). This test was #12 since 2007 and only half of the test were successful, which is normal.
