The General Atomics Aeronautical Systems MQ-9 Predator unmanned air vehicle (UAV) operated by US Customs and Border Patrol (CBP) along the Mexico border crashed in the early morning of 25 April. The $6.8 million UAV was being used to detect illegal immigrants and drug smugglers crossing the US-Mexico border in Arizona.

The ground station lost communication with the UAV at 02:50 in the morning, about 8.5h into a 10-12h mission patrolling the border at an altitude of 12,000-15,000ft (3,600-4,600m). The wreckage was found about 16km (10 miles) north of Nogales, Mexico at around 06:20.

The UAV came down close to its location when the link was lost, suggesting it crashed soon after losing communications. The vehicle did not conduct the recovery procedures programmed into the flight-control computer, which should have resulted in it coming down in a pre-determined area, says the CBP.
