POSSIBLE CAUSE OF THAT CRAZY SKY SPIRAL OVER NORWAY

   Oooo . . . Ahhh . . .  *dead*

Those of you who were trapped in a snowbank yesterday might not have already heard about the strange light that appeared in the sky above Norway (more pictures of that at Geekologie).  Now a possible cause has been hypothesized by the always-brilliant Phil Plait over at badastronomy. (ALWAYS!  Did you just question my adjective?  I will fight you.)  He thinks the spiral was caused by a particles being spewed from a spinning booster rocket.  Below are two videos of the phenomenon over Norway.  The third video is a computer simulation of spiral ejecta from a tumbling rocket.  When viewed from the right angle, it looks very much like the light over Norway.
