Wiltshire's Air Ambulance service is warning lives could be lost if it is unable to raise £2.5 million needed to keep it in the air.
The helicopter is currently shared with the county's police but next year the constabulary will end that agreement - taking with it 2/3 of vital funding.
In a special report, our Wiltshire reporter Robert Murphy asks if the air ambulance can survive.
Paramedics are warning that lives could be lost if Wiltshire's Air Ambulance service cannot raise the money it needs to keep flying.
The county's helicopter is currently shared with the police force - but the constabulary is withdrawing to join another service at the end of next year.
This means the air ambulance needs to raise more than £2million for the service to continue.
Paramedic Ross Culligan has spoken to ITV News West Country:
– Statement from the family of Alistair Porter
We are still concerned about the health of Mike's brother who was badly injured in the accident and air lifted to hospital.
We are in shock and devastated by the loss of our lovely Mike. We are in discussion with the coroner and would ask people to respect our need for privacy at this time. We would also like to thank our incredible friends and family for their warmth and support.”
The 66 year old man trampled to death by a herd of cows in Wiltshire on Monday has been named as Alistair Michael Porter, a retired Senior Lecturer at the University of Edinburgh.
Mr Porter was walking with his brother in a field in Turleigh when a herd of cows attacked them.
His brother was airlifted to Frenchay Hospital near Bristol where his condition is described as stable.
A pensioner who was seriously injured when he and his brother were trampled by a herd of cows in a field at Turleigh in Wiltshire is said to be in a stable and positive condition in hospital, according to a Police spokesperson.
The man in his 70s was airlifted to Frenchay Hospital near Bristol on Monday morning.
His 66 year old brother was fatally injured in the crush and died at the scene.
Wiltshire Air Ambulance Paramedic Ross Culligan said it was 'chaotic' with a lot of panic when he and a colleague arrived at the scene of the incident:
Paramedics performed emergency surgery on a 66-year-old man at the scene, but he suffered a cardiac arrest and was pronounced dead.
His brother, who is in his 70s, also suffered chest injuries.
He was airlifted to Frenchay Hospital near Bristol, where he remains (Tuesday).
