Amelia Brown was left heartbroken at the loss of her 10-year-old pet Monty
Witnesses reported being terrified by the sight and sound of two low-flying USAF F15 jets last week, which are being blamed for spooking and causing the death of many horses.
The jets are believed to have originated from RAF Lakenheath in Suffolk and a probe is underway after the pilots were accused of going on a dangerous 'joyride.'.
But the family of little Amelia Brown have demanded answers after the tot was left heartbroken at the loss of her beloved 10-year-old pet Monty.
Initial reports suggested at least three horses had to be shot as a result – but further victims have now come forward and the scale of the devastation is still being evaluated.
The horses were galloping around fine at 12.30pm, at about 3.30pm the low flying planes were spotted in the area and at about 4.30pm our pony was found in a very bad state
Thousands of residents from across the county have described being affected with the fighters also being accused of unnerving mourners at a wake and leading to some thinking they were going to crash.
Amelia's mother Naomi Brown, 24, of Redruth, Cornwall, says she has no doubt it caused the death of Monty.
She said: "The horses were galloping around fine at 12.30pm, at about 3.30pm the low flying planes were spotted in the area and at about 4.30pm our pony was found in a very bad state.
"After that it all happened so quickly, the emergency vet was called and it took five people to get the pony back in the yard, but it was too late, he had twisted his gut and died before the vet could arrive.

"He was obviously spooked by something and we think that it's too much of a coincidence, after seeing the planes and hearing other people's comments."

Mrs Brown is now teaming up with Claire Sexton, who put out an appeal for information on Facebook after learning of the deaths of several of her friend's horses.
Claire wrote: "Two grey fighter jets flew VERY low over Cornwall on Wednesday, April 12, in the afternoon – at least three horses had to be shot in consequence.

"There may be more – my friend has had to shoot three horses, two with field injuries sustained yesterday, when the two planes passed fast and very low.
"One today, after yesterday it panicked, threw its rider and has become too dangerous for a vet to go near it.
"He sees a pattern – one of the horse owners checked with RNAS Culdrose, but they deny having anything in the air at the time."
Other people commented to say they too knew of horses that also had to be put down following the exercise.
Claire is now hoping that owners may be compensated.
She added: "Let's make this go viral over Cornwall, so that a picture can be built up, and everyone affected can get together.
"Each of these horse-owners must have felt that theirs was an individual, inexplicable tragedy.
"It would be constructive for them, and anyone else affected, to be able to get together, to get answers and, not that it makes up for it, compensation if there was illegal low flying."
Laura Pope said that they flew over the yard so low the whole barn shook
Among those who reported to be affected was Laura Pope, of Truro, Cornwall.
She said: "They flew right over the yard so low the whole barn shook and horses all up set.
"It was terrifying and the noise was nothing short of deafening. This was frightening, dangerous and damn right irresponsible.
"I rang to complain but got the distinct impression not a whole lot would be done and it was made clear we would not get an apology for the unnecessary distress caused.
"I was told to submit any vets bills or bills for damages caused by the incident, but was left very unclear on whether they would be paid or where/whom they should be submitted to!
"There are rules and regulations for flying over areas of livestock that are clearly being ignored resulting in tragedies
"These pilots were not training they were fooling about.
"It's bad enough that people have lost livestock but it could have easily been a much bigger tragedy."
RAF Lakenheath have been approached for a comment.
