The helicopter method utilizes heavy-lift helicopters, such as the Sikorsky S-64 Skycrane, to deliver tower components, equipment, and occasionally workers to mountaintop sites that are otherwise unreachable by road. Tower sections are typically pre-assembled or modularized on the ground, then airlifted to the site, where crews—often transported by helicopter as well—position and secure the components. Although costly, this approach is highly efficient in challenging terrain, minimizing environm
