Not critical, but perhaps a bit of insight. In canada , except for certain purposes like slinging loads, a helicopter must maintain forward movement for safety reasons. I believe the mins are 500ft and 30mph. THis enables the pilot to autorotate if he has engine failure and everyone lands safely. If the helo has no forward speed he is considered " a rock" if the engine quits. So for carrying passengers hovering is dangerous and a helo trys to establish forward momentum as soon as airborn, ie running the length of the field. Ever notice how when an interesting scene is unfolding under a news camera the damn thing won't just sit still and film, but continues to move in a circle.
So they should be moved down the road and just over fly the site.
