Busy day at the Helicopter DZ in Les Bois

Three EC 145 helicopters have been flying today from the Chamonix helipad. The police helicopter carried out training excercises, while the Civil Defense helicopter was on call for mountain rescue. The third helicopter was in Chamonix for a day of technical testing. It was equipped with aeronautical sensors and flew with an aeronautical engineer who tested different devices for flying backwards, with the aim of improving the helicopter's stability.
