The Lincolnshire and Nottinghamshire Air Ambulance is gradually increasing its night operations thanks to the return of some crew members from the NHS frontline.
It will be fully operational overnight on Wednesday, May 20 and between May 22-24 and the charity is increasing the cover for night missions each month.
After launching a trial 24-7 service earlier this year, the charity had said it needed to raise an additional £1.5 million, taking the total required up to £4 million a year.
It is now coming towards the end of the trial and after reviewing the results it will then decide the best way forward as to whether the service needs to be 24/7.
During the coronavirus crisis the crew have worn full PPE to all missions for their safety and that of the patients.
Last week alone the team responded to more than 15 missions across Lincolnshire, Nottinghamshire and Yorkshire.
Of those missions, six were crashes where patients needed medical interventions on scene before being taken to hospital.
The crew attended crashes in Immingham, Bardney, Burgh-le-Marsh and Leake, as well as landing the Ambucopter by the M180/A15 to airlift a patient to Hull Royal Infirmary.
They were also called to two falls on building sites in Boston and Lincoln, with both patients being taken to hospital.
