An aircraft vanished over the Swiss Alps in 1938, killing all 13 occupants. The wreckage was discovered fourteen years later on the slope of Piz Cengalo.

What happened

In 1938, an aircraft disappeared while flying over the Swiss Alps. Because the plane did not reach its intended destination in Milan, search and rescue operations were launched. These efforts continued for several weeks but were eventually suspended without locating any debris or survivors. The 13 occupants of the flight were presumed lost.

Fourteen years after the initial disappearance, on 14 July 1952, a mountain guide located the wreckage. The site was situated on the slope of Piz Cengalo, near the border between Italy and Switzerland, specifically within Italian territory. During the recovery process, several mail bags were retrieved from the debris field and handed over to local authorities.

Findings

The official investigation concluded that the accident resulted from a controlled flight into terrain. The long delay in discovery was attributed to the remote mountainous location of the crash site.
