I find it hard to believe the helicopters fly 500 feet over the pad then descend vertically -- it's hard to see the landing pad when you're directly over it and most pilots descend with something like an and airplane approach to a runway. Of course, if there's tall building around the pad that would be one reason but if there is little in the way of obstructions the pilot will find it easier to land by coming in at an oblique angle.

Agreed.
And while the pilots are WELL TRAINED, it also invites VRS especially in calm wind situations.
