Another thing...
What does the guy with the camera do when the UFO stops in front of the helo? Zooming in as every mortal who has ever used a video camera would do? No, he zooms OUT...

Yeah, it could be that he is searching the perfect plane, or he missed the correct button, or wathever, but in this context, it's somewhat suspicious

.
BTW, I'm using the QuickTime version of the video; you can view it frame by frame, play it forward, backward, slow motion... it shows some details that can't be seen in normal play mode.
