Police Apply For Shoreham Evidence
Investigators into the plane crash at the Shoreham Airshow which killed 11 people are to seek a High Court ruling over access to key information.
Sussex Police have applied to see ``protected material'' held by the Air Accidents Investigation Branch (AAIB), including cockpit recorders and footage, witness accounts, expert reports and documentation.
Aviation law currently blocks access to some material so the Lord Chief Justice Lord Thomas and Mr Justice Singh will be asked to approve its release at the hearing in London on Thursday.
A Hawker Hunter jet plane crashed on to the A27 in August 2015, killing 11 men.
Pilot Andrew Hill was thrown clear from the 1955 fighter-bomber and suffered life-threatening injuries but was later discharged from hospital.
Mr Hill was voluntarily interviewed under caution by police in connection with the accident.
At a pre-inquest review, in March, a spokesman for the AAIB said it had released three special bulletins into the crash with its full report due to be released at the end of the summer.
At the hearing, Detective Chief Inspector Paul Rymarz said: ``There has been a significant delay in obtaining some material in this case because of the legislation that governs the investigation of such incidents.''
He said ``very good liaison'' existed with the AAIB which had ``sought to co-operate to the maximum extent possible under the regulations''.
He added: ``However, police have had to work without the specialist knowledge and assistance of AAIB and instead used the AAIB reports released thus far to inform the investigation.
``Until the relevant court makes a ruling with regards to this material, the police investigation cannot progress effectively, as without it, key evidence is missing and experts are not in a position to provide interpretations.''
