When Chris Patten and the Prince of Wales wave their goodbyes from the deck of the Royal Yacht Britannia, they will not be reduced to mere specks in the distance.
A BBC camera crew on board will relay live pictures to the world and an RTHK crew will be buzzing overhead in a Government Flying Service helicopter.
RTHK technical operations co-ordinator Simon Heung Sai-ho said the departure would be covered using microwave technology.
'The BBC is going to supply pictures from the boat to us. We will try to follow them as much as possible. We will use a microwave link based at the west side of the Convention and Exhibition Centre Extension,' he said.
Captain Mike Ellis, who will pilot the helicopter following the royal yacht, said: 'The primary aim is to cover it past Causeway Bay. We will probably follow her out as far as we can go until coverage is lost. Microwave technology depends on line of sight.' When the helicopter returns to its Kai Tak base, it will receive its new Special Administrative Region insignia. Captain Ellis said a helicopter would also be used to film the Chinese Navy sailing into Hong Kong waters.
However, RTHK live coverage of the PLA arrival will come from Lok Ma Chau only, Mr Heung said.
