Hope I don't get into trouble with this:
From the Martin Baker website:
RAF Red Arrows Incident on 8th November 2011
On 8th November, there was a fatal accident involving the Red Arrows Hawk aircraft XX177 following the ejection of a Mk10B seat.
We have had the opportunity to examine the seat and, while not wishing to pre-empt the outcome of the investigation currently underway, are satisfied that neither a mechanical nor a design fault were to blame for the fatality.
We welcome the opportunity to assist the Lincolnshire Police and the Military Air Accident Investigation Board in identifying the causes of this tragic accident
In the meantime, our thoughts and prayers are with the family and friends of Flight Lieutenant Sean Cunningham who lost his life in this accident.
