Cover Up

So, the mysterious blue light over Norway is being explained as a failed launch of a Russian missile. Here's my take on it. Indulge me good people, my creative juices are overflowing:

This was actually the opening of a wormhole, that transported alien life-forms arriving for their routine observations of life on earth. The trail of light coming from behind the mountain was the photon-key used to open wormholes.

The reason we do not see the ships coming out of the wormhole is because the ships had their cloaking devices activated. However, there was a malfunction because the blue light was suppose to have been invisible.
