How Can It Be Too Hot To Fly?

The video discusses the impact of extreme heat in Phoenix, Arizona, where temperatures reached 120 degrees Fahrenheit, leading to flight cancellations. The cancellations were due to insufficient air density, which affects the lift needed for planes to take off. The video explains the principles of lift, the role of air density, and how higher temperatures can reduce air density, making it harder for planes to fly. It also covers how temperature affects airplane engines and the safety measures airlines can take, such as reducing weight. The video concludes by highlighting the challenges of living in extremely hot climates.
