A Virgin Atlantic engineer died of a traumatic brain injury after an explosion as he worked inside a plane fuel tank, an inquest heard. Buxton was one of two Virgin Airlines' technicians who were examining a fuel leak on a Boeing 787 900 on 11 June at about 08:45 BST. A spokesman for Aviation Policing told the court: "Both technicians wore breathing apparatus to protect them from any residual fuel fumes whilst inside the fuel tank." The spokesman said there was "a non-combustion explosion" while Buxton was inside the fuel tank. A forensic post-mortem examination, carried out at the request of the police, found Buxton had suffered a traumatic brain injury – a craniofacial trauma.
