Southend Vulcan Stretches Her Legs Southend Vulcan Stretches Her Legs On December 12th, the Vulcan Restoration Trust’s exercised their Avro Vulcan B.2 XL426 on the runway at London Southend Airport in Southend-on-Sea, Essex. The locally-based organization maintains one of just three Vulcans which can still move under their own power on the ground. XL426 performed four, full-power taxi runs over the course of the day, providing two groups of visitors a rare treat to witness the raw power of the mighty Vulcan’s Rolls-Royce Olympus engines at ‘max chat’ as the Cold War bomber roared down the runway in a simulated take-off run.
