UFO Disguised As A Helicopter - Its Blades Do Not Move

This helicopter is probably a UFO but disguised. Its not the frame rate matched at speed. Its not a model, it is what it is! Theres many cases of machines, vehicles that were disguised. This is one of them times when everything doesn't match up right?
What is this, it's really baffled us? We thought a helicopter had to use it's propeller blades to fly? Are we missing something here? Seriously is there a helicopter out there that doesn't need to use it's rotating blades to fly? We are absolutely stumped by this one because everything about this defies logic? Is it a #UFO disguised as a helicopter?

Unfortunately the video no longer exists. Sorry.
