Communication Towers and Safety Measures

The video explains the importance of communication towers and the role of red lights on them. Marty Cooper invented the first cellphone towers in 1982, which were crucial for communication. Initially, towers lacked lights, leading to accidents with aircraft, especially in foggy conditions. Red lights are used because they have a higher wavelength, making them visible from afar, thus preventing accidents. The video concludes with a call to action to like and subscribe.
