Saturday 29th May will see the Vanguard at Brooklands perform engine runs and (if possible) taxi along the runway. This will be the last time the Vanguard will move under its own power as it is scheduled to be moved inside the museum next week where there will be no room to taxi her.
All of course dependent on servicability, fire cover etc. For more info see the museum website:
