A privately operated drone flying in restricted airspace struck a search-and-rescue helicopter over Kerrville, Texas, on Monday, city officials said. The aircraft was supporting flood response operations when the collision forced it to make an emergency landing, taking what authorities described as a critical piece of equipment out of service. The airspace above Kerrville has been under a Federal Aviation Administration temporary flight restriction since severe flooding of the Guadalupe River began on 4 July. Kerr County has reported 84 deaths and more than 100 people still missing. Officials warned that any unauthorized aircraft, including hobby drones, risk grounding manned flights essential to rescue and recovery work. City Manager Dalton Rice urged residents to keep personal drones grounded until the emergency ends, noting that violating federal restrictions could lead to enforcement action. The FAA said only operators involved in the official response may receive expedited approval to fly in the zone.
