including leeds general infirmary, hull royal infirmary and james cook university hospital in middlesbrough. in october 2007, a second base was opened at sheffield city airport. the airport then closed at the end of april 2008, but a heliport facility was still provided for the use of the air ambulance and the south yorkshire police helicopter. in november 2010, the operational base for the sheffield-based aircraft was moved to bagby airport near thirsk. the second aircraft then made another move in march 2012 to raf topcliffe, which it shares with the 645 volunteer gliding squadron. in 2012, planning permission was granted for a new operating base within the nostell priory estate for the yorkshire air ambulance. the new site, including a hangar and aircrew accommodation, became operational in 2013. it replaced the facility at leeds bradford airport. former helicopter md 902 explorer g-sash in derbyshire one helicopter (formerly helimed 99, registration g-sash) was based at a hangar at leeds bradford airport (egnm), which enabled servicing and maintenance to be carried out overnight, leading to even quicker response times in many parts of the county. until 2016, the helicopter was located at nostell priory near wakefield, where it had a newly renovated hangar and accommodation for crew, plus offices on site. the aircraft was then replaced by g-yaac (helimed 99), a new £6 million airbus h145. the second helicopter (helimed 98, registration g-cems) was originally based at sheffield city airport but moved in march 2012 to raf topcliffe near thirsk. a spokesman for the charity commented: "what we're looking to do is provide the very best coverage for the whole of yorkshire, for the five million population. the people of yorkshire are better served with an aircraft at thirsk and one at leeds bradford." in 2016, the second helicopter was replaced by g-yoaa as part of the air ambulance's fleet renewal programme. aircraft airbus h145 g-yaac landing at leeds general infirmary. the first helicopter was an mbb bo 105, but in 2005 they started using an md 902 explorer. the explorer was used extensively in an air ambulance capacity throughout the uk, but is gradually being phased out of service for renewal purposes. it has five rotor blades to ensure a smooth flight which can prove particularly beneficial for patients suffering head or spinal injuries. twin turbine engines give it a cruising speed of 154 mph (248 km/h), and skid landing gear allows it to cope with all types of terrain. its compact dimensions allow it to land in confined spaces, yet it has room to carry one stretcher patient. it contains all equipment found on any front-line ambulance plus other special items. they have to land in a great variety of places: in one call, the only land near enough and flat enough to land on was the top of whernside at 2,415 feet (736 m). in 2016, the two existing helicopters were replaced by two new airbus h145, which are registered as g-yaac (based at nostell priory) and g-yoaa (based at raf topcliffe). the new h145 helicopters cost at total of £12 million and offer lower operational and maintenance costs, as well as having night capability enabling longer hours of operation. they are expected to serve yorkshire for the next 20 to 25 years. the air ambulances appeared on the bbc one programme helicopter heroes, on
