A mother has told the BBC of her disbelief over her daughter's death, after an ambulance went to the wrong address.
Elouise Keeling, 14, had a severe asthma attack and collapsed at RAF Brampton, near Huntingdon, last June.
Coroner David Morris ruled in March that her death "could not have been avoided by any more timely arrival", but her mother Karen Keeling told BBC Radio Cambridgeshire the verdict was not fair.
The East of England Ambulance Service said it was "deeply sorry".
