Over a mile wide UFO triange appeared over Russia

A huge triangle shaped UFO howered over Moscow's Kremlin.

Some people suggested it's an air balloon or stunt, but a spokesman for aerospace experts Jane's News said: "We have no idea what it is."

There are 2 videos available, one is filmed by day and one at night.
I'm pretty sure it's just another hoax since there are only 2 videos available. There would be thousands of videos and pictures if an object that large would really appear in the sky. There's no doubt we would get live footage too.
