UFO Flying In To A volcano

This is a brilliant video showing a few things that go against everything we know about materials and physics? 

There shouldn't be anything able to fly in to a volcano then fly out presumably?

Then there's the materials, what is this UFO made of, Superman's spandex!

This flies in the face of everything we know about known materials, that's why I think this is real.

Or, a hoaxer is playing on the impossibility of this, versus your want to believe so that you believe.

Night time footage on a night vision webcam of a UFO flying right in to the mouth of a volcano in Mexico looks absolutely strange, improbable, suspicious and the obvious question is how? How can anything survive them temperatures? This is incredible footage if its real, but if this is real then we know where material technology is going in the future. Man now knows this is possible so we will not stop until we create it. Maybe?
