A thankful mother will be jumping 13,000ft out of an aeroplane today to raise money for the East Anglian Air Ambulance who rescued her two-year-old son after he broke his leg in the middle of a field.

Emily Bishop, of Shipmeadow, between Beccles and Bungay, was enjoying a picnic with her five children and friends in the summer holidays when her son, Toby, fell off his sister's bike and suffered a broken thigh bone.

Stuck in the middle of the countryside away from any roads, Toby was rescued by an air ambulance crew who put him to sleep, strapped him on a spinal board and flew him to the Norfolk and Norwich University Hospital where he spent a week in traction before being put in a spica cast.

Ms Bishop said: 'As soon as I looked at him I thought he's really hurt himself.

'His eyes started going and that was a bit scary.

'I called 999 and we established we weren't anywhere near a road. Because he had fallen we didn't know what injuries he had, so I couldn't move him.

'I didn't have a lot of phone battery left so they said they would call me back and then we heard the helicopter, so we were all jumping in the field waving our arms.'

Ms Bishop said she was not sure how paramedics would have reached them without the air ambulance.

She said: 'One minute we were having a lovely picnic and the next minute it was just surreal.

'They were absolutely fantastic, so lovely and supportive and afterwards they gave me their card so I could let them know how Toby was.'

Toby is now back at home with his family and is on the mend.

Ms Bishop said: 'He's been a bit frustrated but he taught himself how to crawl in the cast after a day of being home from the hospital.

'He keeps telling people 'mummy is going to jump out of a plane', so I think he's quite proud.'

Ms Bishop will be doing a tandem skydive at Beccles Airfield as part of UK Parachuting's world record attempt and hopes to raise as much money as possible for the air ambulance.

She said: 'I wanted to do the jump as a way of saying thank you.

'I've always said you never know when you will need them and now I know how valuable they are.'

Spectators are welcome to support Ms Bishop at the airfield, who will be jumping along with 178 other people throughout the day in a bid to break the world record.
