Bosses at the Warwickshire and Northamptonshire Air Ambulance that includes the Corby area - say a new 24/7 era for them is another milestone.
The cause, which began in two thousand three, supports NHS ambulance teams with extra cover through helicopters and rapid response vehicles.
It relies solely on donations from people and companies- WNAA leaders now says it's able to provide cover around the clock all year round following a "substantial investment".
It follows a two year project to find out what demand for services was like between 2 and 7 am.
The charity adds that each of their operational bases has also been upgraded to support staff.
