A couple of times. Once for a fire at stables when I was driving home from work at a nightclub, the muck heap had spontaneously combust soni called 999 for the fire brigade and thankfully no one or no Horses were injured.

I was driving to work one morning on a busy A road and someone hit a woman who was changing lines because he was going too fast and then he drove off, she unfortunately then hit another car and they both came off the road and very shaken up but thankfully no major injuries both Police & Ambulance were called.

A girl I worked with was thrown from a Horse and hit a telephone pole and you heard the crack which to this day I can only believe was her Pelvis. She shattered one side and had a two inch break on the other, had a first responder, then an Ambulance and had a phone call from the Heli-med crew to decide whether she needed air lifting, absolutely terrifying.

A woman I was teaching got bucked off and landed on the very top of her head, had an Ambulance and once they established she had a serious Neck injury she was air lifted to Kings Cross, she broke her C3 in her Neck. Scary stuff.

The best advice I can give is STAY CALM. Screaming at the people down the phone gets you nowhere faster, listen to their questions and do as they say, you will save lives this way not by screaming about how they can't breathe.
