Investigation Summary
The Caproni Ca.48 was a pioneering attempt to repurpose military technology for civil use following World War I. The aircraft was a conversion of the Ca.42 bomber, featuring a double-deck cabin designed to carry up to 23 passengers. On the day of the accident, the aircraft had successfully completed a morning flight from Milan to Venice. During the return leg in the late afternoon, the aircraft reached the vicinity of Verona. Eyewitness accounts were consistent in describing a sudden instability in the wing structures, followed by a total collapse. The failure was so severe that several passengers reportedly jumped from the falling wreckage in a desperate attempt to survive. The debris field was found scattered over a radius of more than 400 meters, indicating a high-energy mid-air breakup. While structural failure due to wing flutter is the most widely accepted explanation, a secondary historical theory suggests the disaster may have been triggered by a passenger dropping a camera, which then struck a propeller and was projected into the airframe. Furthermore, the exact death toll remains a subject of historical debate; while 14 is the most cited figure (2 pilots, 5 journalists, and 7 mechanics), other records suggest 15, 16, or 17 fatalities.
Final Conclusions
The crash was attributed to a structural failure of the wings. While the exact engineering cause was not documented with modern forensic detail, the observation of wing 'flutter' followed by collapse strongly suggests aerodynamic instability or structural fatigue in the triplane's complex bracing system. The aircraft was destroyed and written off.

Airframe & Maintenance
Systems & Failure Modes
Wing Structure
The aircraft was a triplane design; eyewitnesses reported the wings fluttering and collapsing, indicating a catastrophic loss of structural integrity.
Liberty L-12 Engines
The aircraft was powered by Liberty L-12 engines, though there is no evidence suggesting engine failure contributed to the crash.
Interesting Facts
- 01It was the first commercial aviation disaster in Italian history.
- 02The aircraft was a triplane conversion of the Caproni Ca.42 heavy bomber.
- 03The passenger list included five prominent Italian journalists and seven Caproni company engineers.
- 04Wreckage was scattered over an area with a radius of over 400 metres.
- 05The aircraft featured a double-deck cabin with large windows, a novelty for 1919.
Safety Actions & Advisories
Suspension of Civil Operations
Following the disaster, the Caproni company suspended its civil passenger flight operations. The Ca.48, despite the initial excitement, likely never entered formal scheduled airline service after the accident.
Known Controversies & Unanswered Questions
Disputed Death Toll
Reference ↗While the most immediate reports cited 14 fatalities (2 pilots, 5 journalists, and 7 mechanics), other historical sources have placed the death toll at 15, 16, or 17 without definitive explanation for the discrepancy.
Camera Strike Theory
Reference ↗A secondary historical theory suggests the disaster was not caused by inherent structural failure but by a passenger dropping a camera, which then struck the central engine's propeller and was projected into the airframe, triggering the breakup.
