THE Royal Air Force 28 Squadron will stage one of its last fly-pasts today to mark its 80th anniversary as it approaches the last 18 months of service before being disbanded. The squadron, the only one in the Air Force never to have served operationally in Britain, faces an uncertain future after the change of sovereignty. Apart from any role it may play in the handover celebrations, today's fly-past could effectively be its last major non-operational event. 'It will be our chance to celebrate our 80th anniversary and also the last 18 months in Hong Kong,' said Squadron Leader Dick Barton. 'Hong Kong could be our last area of duty. The squadron's future is unknown after we finish here.' The squadron's standard will be laid up in the RAF church St Clement Danes in London where it will remain until it is reformed. 'The RAF policy is to use low numbers so there is a good chance it will be re-formed,' Squadron Leader Barton said. All the men will transfer to other units. The squadron has been based in the territory for 46 years. It was formed at Fort Grange, Gosport, in the south of England on November 7, 1915, spending its first 18 months as a training squadron before transferring to Italy and patrolling the frontline. When it moved to Hong Kong in May 1949 it had Spitfire Mark VIII aircraft. It flew its first helicopters - Whirlwinds - in March 1968 after disbanding briefly 14 months earlier.
