Has anyone been prosecuted over the crash?

No. Pilot Andrew Hill is being investigated by police over possible manslaughter by gross negligence. Officers have questioned him twice. He has not been arrested.

Will anyone be prosecuted?

We do not know yet. Police have amassed some 25,0000 documents in the course of their investigation. Officers are now in the process of consulting on their evidence with the Crown Prosecution Service (CPS) and the investigation is 95 per cent complete.

What happens when the CPS looks at the case?

The case will be considered by a senior lawyer in the special crime division. They consider whether there is sufficient evidence to secure a conviction and that the evidence would meet the burden of proof and is in the public interest.

Who is leading the police investigation?

Detective Superintendent Adam Hibbert, head of the Surrey and Sussex Major Crime Team. He worked through the ranks to become a senior investigating officer in the major crime in 2004. He joined the force, based at Hove, in 1987. He took over as the senior investigating officer in the Shoreham case in April from Detective Chief Inspector Paul Rymarz who has left his role for a position with another force. Both worked together on the investigation into the murder of Don Lock in Worthing one month before the Shoreham Airshow crash.
