1919 Verona Caproni Ca.48 crash

On August 2, 1919, a Caproni Ca.48 airliner crashed at Verona, Italy. All aboard died, with various sources placing the death toll at 14, 15, and 17. It was Italy‘s first commercial aviation disaster and the earliest heavier-than-air airliner disaster in history.

The Caproni Ca.48, owned and operated by the Caproni company and flown by two Italian military pilots, took off from the company's home airfield at Taliedo, a district of Milan, Italy, on Saturday, August 2, 1919, at 7:30 a.m. local time for a flight to Venice, where it arrived without incident at 9:22 a.m. After spending the day at Venice, the aircraft took off at 5:00 p.m. for the return flight to Taliedo.
Eyewitnesses reported that as the airliner passed near the airfield at Verona at an altitude of 3,000 feet , its wings seemed first to flutter and then to collapse entirely. Several of the people on board jumped from the aircraft to their deaths before it crashed. There were no survivors.
