I'm not sure how he managed to get approval to use this at a race meeting.
I'm sure health and ****** safety would put a stop to this now.
There were signs of old Canon stickers on the balloon, so I guess it was once a promotion item that got fitted with a radio controlled servo-driven mount and low power TV transmitter to the photographer on the ground at the other end of the rope.
I'm sure he got a unique viewpoint on the race and the fans.
