On 3 December 2017 XL426 carried out a slow speed taxy test at London Southend Airport.
XL426's captain for the test was Group Captain Bill Burnett RAF Ret'd and we had a guest Crew Chief in the shape of Taff Stone from the Vulcan to the Sky Trust helping on the ground.
The post engineering tests involved XL426 carried out two power runs on the runway to a slow speed before returning to the hangar apron.
