Red Arrows death: Ejection seat firm 'put lives at risk'
An ejection seat manufacturer - prosecuted over the death of a Red Arrows pilot - put many pilots at risk over a lengthy period, a court heard.
Flt Lt Sean Cunningham, 35, was ejected from his jet while it was on the ground at RAF Scampton in 2011.
The parachute on the seat did not then deploy and the airman was fatally injured, Lincoln Crown Court heard.
Martin-Baker Aircraft Ltd previously admitted to breaching Health and Safety law.
Earlier, the court heard how the Middlesex-based company has already agreed to pay £550,000 in prosecution costs as a result of the guilty plea.
However, in a statement the company said: "It should be noted that this was an isolated failure relating to the tightening of a nut... by RAF Aerobatic Team mechanics."
It added its ejection seats were in use by 92 air forces and had saved more than 7,000 lives.
But Rex Tedd QC, for the prosecution, said: "There was a risk to many pilots over a lengthy period. The defendant's failure was anything but isolated."
"If the pilot was ejected from the Hawk aircraft, two shackles would not release from one another and would jam together and the main parachute would not deploy," he said.
"The pilot would be several hundred feet in the air and there could only be one result of that, and that is the pilot's death."
Mr Tedd also told the court: "Sean's two biggest fears in life were being ejected from an aircraft, and the injuries that he would sustain, and dying at a young age. Horrifically he experienced both."

An earlier inquest into Flt Lt Cunningham's death heard the Iraq war veteran, who grew up in Coventry, had been carrying out pre-flight safety checks in his Hawk T1 jet when the seat fired.
It emerged during the hearing the ejection seat firing handle had been left in an unsafe position meaning it could accidentally activate the seat.
His parachute failed to deploy because a nut and bolt had been fastened too tightly.
Martin-Baker had been aware of the possibility of the parachute mechanism jamming as early as 1990, the inquest was told.
The hearing continues.
