On December 7, 2006, a Virgin Atlantic Airways Boeing 747-400, registration G-VHOT, experienced instrument and stick shaker problems after takeoff from London Heathrow Airport. The pilots declared an emergency, dumped fuel, and returned to the airport. The right air data computer was replaced; however, the stick shaker problem occurred again on the subsequent takeoff roll and the takeoff was aborted.

The incident is being investigated by the UK Air Accidents Investigation Branch.
