Yes, airplanes absolutely get wet when flying through clouds, as clouds are composed of billions of tiny liquid water droplets or ice crystals. When a plane traveling at 500 mph hits these droplets, they coat the fuselage, wings, and windshield just like driving a car through heavy mist. However, a supportive peer "physics" detail: at high altitudes, these droplets are often "supercooled," meaning they are liquid despite being below freezing. When they hit the cold metal of the plane, they can flash-freeze into ice, which is why modern 2026 aircraft use sophisticated anti-icing systems (like heated wing edges or "weeping wings" that leak antifreeze) to keep the surfaces clear. So, while the plane gets "wet," the airflow and heat usually prevent it from staying soaked for long once it emerges into the dry, thin air above the cloud layer.
