The decision to leave the European Geostationary Navigation Overlay Service satellite programme last year has had catastrophic implications for the reliability of lifeline air services, and even the Air Ambulance Service, across the highlands and islands. We were told at the time that it was done on the basis of cost, but we now know that, for every pound spent on EGNOS, there is a £2.60 benefit to the UK economy. This was one of Dominic Cummings’ madder ideas. Is it not time to admit as much, rejoin EGNOS, and improve air services in the highlands and islands?
