A pilot plunged 1,000ft to her death in front of her horrifed boyfriend after both wings of her glider fell off in midair.
Amy Barsby, 25, had just launched her craft at the start of a university competition when the catastrophic accident happened.
The PhD student's glider plummeted to the ground at Bicester, Oxfordshire, leaving her with multiple injuries.

Multiple injuries: Amy Barsby - seen here after her first field landing - died when the wings fell off her glider as she took part in a university competition
Her boyfriend Bruce Duncan, a gliding instructor, called an ambulance but there was nothing paramedics could do.
It is understood that Miss Barsby, who has a younger sister called Lorna, died instantly.
Her father Steven today told said the family had been shattered by her death.
Speaking from the home he shares with his wife Helen and their younger daughter, in Longridge, near Preston, Lancashire, he said: 'It was all over in a few seconds.
'It seems like (the wings) more or less came away at the same time and then it plunged down to the ground.
'Bruce witnessed the event and we understand that his first reaction was to instantly call the emergency services.
'Fortunately he was prevented from seeing Amy at the crash scene but he is struggling to make sense why such a lovely young woman has been taken from us at such a young age.
'The emergency vehicle was on scene very quickly and I think it was apparent that she died instantly.'
Miss Barsby had driven down to her parents' home with her partner and a group of friends on Friday night.
Multiple injuries: Miss Barsby had been flying for ten years and was hooked on the sport
Her father said she had been 'very happy' and looking forward to the competition.
The party then went on to Bicester on Saturday ahead of the contest on Sunday.
After arriving at the airfield, Miss Barsby and Mr Duncan assembled the glider, which had been transported in a trailer.
She then undertook a successful test flight to check that the craft was working before lining up for the first round of the competition.
Gliders are launched by a tractor type machine that pulls them along until the air gets under the wings, carrying them up to1,000ft.
Miss Barsby, a silver grade pilot with ten years experience of flying, had reached the correct height to fly when Mr Duncan saw the craft disintegrate.
The Air Accident Investigation Bureau (AAIB) has launched a full investigation into the crash.
The investigator has told the family that he was satisfied the craft was constructed correctly for flight and that there had been a 'catastrophic' failure.
Miss Barsby had become hooked on flying gliders while she was a schoolgirl.
'When I saw her face when she stepped out of her first glider there was a look of ecstasy that she had so we knew then that we couldn't dream of stopping her from doing it,' her father said.
'Amy loved walking, skiing, horse riding, she was treated for her 21st birthday by her friends from uni to a white water rafting experience. She enjoyed the adrenalin rush that she got from that.
'She was a very sensible girl though, she was always very safety-conscious.
'She was never reckless, always very measured in what she did, but she did enjoy herself in every way.
She packed such a lot into her short life.'
'Her legacy for us as a family will be the memories that we will have of her. She has been taken from us at such a young age and that's so unfair.'
Mr Duncan, who is originally from Aberden, is being comforted by his mother and sister.
He met Miss Barsby when they were both studying at the University of Edinburgh
She had graduated with a degree in archaeology in 2003 and was studying for a PhD at Queens University, Belfast.
The couple had bought a house together in Edinburgh last year and had adopted a rescue dog.
Miss Barsby's funeral will be in the Scottish capital, a place her family said she loved.
