"The feasibility of broadcasting the TT races live has always been severely limited by the nature of the 37-mile TT circuit. The challenge of transmitting live images from multiple remote locations and a helicopter has so far been seen as the main commercial, as well as technical, hurdle."
Never a truer word said but I hope they pull it off. 2 Helicopters maybe and live camera feed where the radio commentators are? Some fixed cameras with automatic rider tracking? It'll be interesting.
