More than 350 UAVs were lost during a practice light display show in Melbourne, Australia, on July 14, ahead of a scheduled performance for the opening of the women’s World Cup.
The UAVs appeared to stop mid-show and plummet into the Yarra River. Divers have since fished out hundreds of the UAVs.
According to the Resilient Navigation and Timing Foundation, the likely cause of the mass-crash was caused by interference with GPS signals. This incident shows that having multiple and robust navigation sources is important for safe UAV operation.
