The Air Line Pilots Association (ALPA), the largest pilot union in the United States, has formally called on the Federal Aviation Administration (FAA) to block the startup Rainmaker Technology’s proposal to conduct drone-based cloud seeding using pyrotechnic flares. ALPA argues that deploying drones equipped with flare dispensers in controlled airspace poses serious safety risks to manned aircraft and communities on the ground, urging the FAA to reject the plan unless stringent safety and environmental requirements are met[2][4].

Rainmaker Technology plans to use unmanned aerial vehicles (UAVs), specifically its Elijah quadcopter drones, to disperse silver iodide flares into clouds to induce precipitation, a process known as cloud seeding. The company claims this drone-based approach could revolutionize water management by being more precise, cost-effective, and scalable than traditional crewed cloud seeding flights, which have long been employed in the Western U.S. to support agriculture, irrigation, and ski resorts[2][3].

However, ALPA highlights several critical concerns. The drones are proposed to fly up to 15,000 feet above mean sea level, well into controlled airspace used by commercial and IFR (instrument flight rules) traffic. This altitude far exceeds the standard 400-foot limit for small drones under FAA Part 107 regulations, requiring multiple waivers and close coordination with air traffic control. The union warns that drones lacking certified detect-and-avoid systems, operating in turbulent, icing-prone cloud conditions, could lead to midair collisions or loss of control. There is also worry about the potential for flare debris—both burn-in-place and ejectable casings—to become hazardous foreign object debris, possibly causing fires or damaging aircraft[2][4].

The FAA is currently under pressure to modernize drone regulations, following the 2025 White House executive order “Unleashing American Drone Dominance,” which promotes innovation in drone technology across sectors such as agriculture and environmental management but demands rigorous safety assessments. ALPA’s letter to the FAA stresses that allowing cloud-seeding drones to operate beyond visual line of sight in busy airspace without fully addressing these risks could lead to catastrophic incidents[2].

Rainmaker maintains that their drone flights will primarily occur over rural areas and private properties with established permissions, and that their operations will be overseen by trained remote pilots employing multiple safety checks. The company argues that drone cloud seeding could significantly aid drought mitigation and water supply management amid growing climate challenges, and points to international trials in places like Rajasthan, India, as evidence of the technology’s promise[1][3].

Public and regulatory debate thus continues to intensify, balancing the potential environmental benefits of innovative drone cloud seeding against aviation safety and environmental risk concerns. The FAA’s forthcoming decision on Rainmaker’s exemption applications will set a critical precedent for how uncrewed aircraft are integrated into weather modification efforts in the U.S. and possibly beyond[1][4].
