Sion base

The Sion base is the latest of 14 Rega bases throughout Switzerland. Since December 2021, the crew in Sion has been strengthening Rega's national network. 

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.
