Swiss search parties found an air force fighter jet that went missing on Monday during a training exercise but were still trying to find the pilot, the Swiss defense ministry said on Tuesday.
The plane, a one-seat F/A-18C, crashed near Susten in central Switzerland. Bad weather was hampering the search in mountainous terrain.
The incident marks the third time the Swiss Air Force has lost one of its F/A 18 jets in the past three years.
A pilot was injured when an aircraft went down in October 2015 in southeast France, while another F/A 18 crashed in Switzerland in 2013.
