The stationing of an helicopter in Sion was carried out in collaboration with the local helicopter firm, Héli-Alpes SA, in whose hangar the Rega helicopter was based. The Rega crew is on standby around the clock and can thus take off within just a few minutes, including at night, in order to bring medical assistance wherever it is needed.

On 17 December 2022, the new Rega helicopter with the registration HB-ZQO went into service at the Sion base. Similarly to all Rega’s helicopters, the rescue helicopter in Sion is equipped with a rescue hoist and can be deployed for Rega’s entire scope of operations – including transporting intensive-care patients and new-born or premature babies.
