Italian Air Force — Flight MM54386

An Italian Air Force Aermacchi MB-326 trainer jet crashed into the Gaetano Salvemini Technical Institute after being abandoned by its pilot due to an in-flight fire and engine failure. The pilotless aircraft struck a first-floor classroom where a German lesson was in progress, killing 12 students and eventually a teacher, while injuring 88 others. The pilot, who ejected minutes before impact, survived with spinal injuries. The disaster led to a high-profile criminal trial of the pilot and two superior officers, who were initially convicted of manslaughter but later acquitted on appeal.

Report

Investigation Summary

The aircraft took off from Verona Villafranca Airport at 09:48 for a mission testing anti-aircraft radar systems. Approximately 34 minutes into the flight, the engine began experiencing technical difficulties near Ferrara. The pilot, Sub-lieutenant Bruno Viviani, initially considered landing at Ferrara, but determined the 600-meter runway was too short for the MB-326. He opted to divert to Bologna Airport, approximately 40 kilometers away. During the approach to Bologna, the situation deteriorated rapidly: Viviani reported a total engine failure, an on-board fire, and unresponsive flight controls. After attempting to steer the jet toward uninhabited fields, he ejected at 10:31. The aircraft continued in a pilotless glide for two minutes before striking the school building at 10:33. The impact created a seven-meter-wide hole in the school's wall and triggered a massive fuel-fed fire that trapped students and staff on the upper floors.

Final Conclusions

The investigation was conducted by the public prosecutor's office as Italy's aviation safety agency (ANSV) had not yet been established. The prosecution focused on the pilot's decision-making, arguing he should have steered toward the Adriatic Sea rather than a populated area like Bologna. In 1995, the pilot and two colonels were sentenced to 2.5 years in prison for involuntary manslaughter. However, the Court of Appeal overturned these convictions in 1997, ruling the defendants' actions were faultless and the crash was an inevitable tragedy resulting from a mechanical emergency. This acquittal was finalized by the Court of Cassation in 1998.
