The Great North Air Ambulance was called into action in north Northumberland twice in one day at the weekend.
The Guardian of the North helicopter was first called to Otterburn at around 2.10pm on Sunday.
A North East Ambulance Service (NEAS) rapid-response paramedic was first on the scene of a man who was suffering a heart attack.
He was treated at the scene by the air-ambulance doctor and paramedics before being flown to Newcastle RVI. His condition on arrival at hospital was described as critical.
The same helicopter was then called to Ellingham at around 4pm after a man lost control of his quad bike and fell down into a quarry. He was treated by NEAS paramedics and the air-ambulance doctor at the scene before he was flown to Newcastle RVI with severe injuries. His condition on arrival at hospital was also described as critical.
A post on Facebook last Thursday stated that the air ambulance had landed at Alnwick Rugby Club at around 9am. However, the service has confirmed that the helicopter seen was not theirs.
