Swiss authorities have confirmed that all 20 passengers and crew onboard a vintage Junkers JU-52-HB-HOT were killed when the aircraft crashed in the Swiss Alps on Saturday. The plane was flying from Locarno, near Switzerland's southern border, to the airline's base in Dübendorf, a suburb of Zurich.
While no early explanation for the cause of the crash has been suggested, the accident happened only hours after a family of four were killed farther west in the Alps when their small aircraft crashed.
JU-Air owns three decommissioned former Swiss Air Force Junkers JU-52 aircraft and all future flights have been suspended. The airline was established in 1982 and with its three mid-century Junkers Ju-52 aircraft provides sightseeing, charter and adventure flights.
According to Reuters, wreckage of the plane was in a basin at 2,450 metres (8,000 feet) above sea level surrounded on three sides by peaks.
The Federal Office for Civil Aviation closed the airspace above the crash site and access to popular hiking trails in the surrounding area has been blocked.
