1. Zipline - In 2019, the FAA granted a waiver to Zipline, a drone delivery company, to operate beyond visual line of sight (BVLOS) in North Carolina. The waiver allowed Zipline to deliver medical supplies, such as blood and vaccines, to hospitals and clinics in rural areas.
2. BNSF Railway - In 2020, the FAA granted a BVLOS waiver to BNSF Railway to conduct drone operations for inspecting rail infrastructure, including bridges, tracks, and tunnels. The waiver allowed BNSF Railway to conduct these operations over long distances and in remote areas, improving efficiency and safety.
3. Terra Drone - In 2021, the FAA granted a BVLOS waiver to Terra Drone, a global drone service provider, to conduct drone inspections of a wind farm in Texas. The waiver allowed Terra Drone to operate drones beyond visual line of sight, enabling them to inspect the entire wind farm more efficiently and safely than with traditional methods.

These case studies demonstrate how companies are using drone technology to conduct a variety of operations that were previously difficult or impossible to do with traditional methods. Through the FAA waiver process, these companies were able to demonstrate that their operations could be conducted safely and effectively, and received approval to operate beyond the usual regulatory limits.
