The wife of a millionaire who died when his jet fighter trainer crashed on to a motorway is to sue the instructor who survived the accident.

Mother of three, Tina Clark blames poor training and poor safety regulations for the tragedy. The brakes failed on her husbands Gary’s plane and it landed at Duxford, Cambridgeshire.

It slid down an embankment and across the M11, coming to rest on the southbound carriageway.

Mr Clark, 46, ejected but his parachute did not have time to open and he was killed as he came down in a nearby field.

His instructor, Andy Gent, remained in the Czech-built £165,000 L-39 jet and escaped with minor injuries.

Yesterday, Mrs Clark 32, said she feared that there could be more deaths if safety standards are not improved.

“I couldn’t stand the thought of another woman being widowed like me because we don’t learn from my husband’s death. That would be too much to take. Others will die unless tough regulations are introduced for training people to fly in fighter planes, I’m sure of it”, she said.

Mrs Clark plans to sue Mr Grant and the firm that employs him, RocketSeat.

She also wants High Court approval to re-open the investigation into the crash.

The widow said that she wanted compensation from the instructor and RockSeat because she believed that someone else must be held accountable for the crash on June 2nd 2002.

But she added “that it is the whole system that needs to be changed. I want recommendations to be made to the Civil Aviation Authority to tighten regulations.

“I really wish it had been a freak accident, but it wasn’t. It was an accident waiting to happen”.

Mr Clark, who owned a computer firm, was the co-owner of the aircraft with a friend.

He was an experienced pilot, but had only been flying the jet for a few weeks before the crash.

An inquest last October heard that when the two-seater military jet came in to land, Mr Clark reported the aircraft’s brakes and failed so Mr Gent tried to steer the plane to the right.

But it ran down a 15ft embankment onto the M11 and across the central reservation before ending up on the southbound carriageway.

Mrs Clark said she and her children James, eights, Katerina, six and Jessica, two, were still coming to terms with the tragedy.

“People keep telling me that time will act as a healer, but that hasn’t been the case for me. My children keep saying “Daddy can’t be dead because we need him”.

U.S. born Mrs Clark married her husband seven years ago after meeting him in a Washington hotel where she worked as a concierge.

“He was a very good father and a wonderful husband”.

“He wrote me his last love letter month before he died. It was a fairytale that has turned into a nightmare”.

Mrs Clark’s solicitor, Desmond Collins said: “Mr Clark was a young man, who was earning a lot of money, so one would expect a compensation claim to be fairly considerable”.

A Civil Aviation Authority spokesman said “We have some of the tightest regulations in the world for the operation of ex-military aircraft”.

He added that an independent crash investigation found no fault with the safety regulations.
