Note this helicopter is still flying her american numbers. This was a small helicopter which was flying aroud watching the start of the Trans-Atlantic Sailing Regatta. Take a look in sailing vessels.
This is the un-cropped version of the last photo of Flight 721. This gives you an idea what the floating heli-pad looks like. They land and take off from the center, and parking for one on each corner of the pad.
This is the Vancouver Harbour Heli-pad, which is managed by Helijet International Incorporated. I believe that the helicopter is about to take off at this point.
