Have you ever seen a plane being de-iced? Plane de-icing is a crucial winter safety procedure where heated fluid, typically glycol and water, is sprayed on wings, tail, and fuselage to remove ice, snow, or frost before takeoff. I've only read this in theory but now, I have witnessed it. Might be uninteresting to some, but I find this amusing. ☺️ Reminds me of the many learning experiences we have when traveling.
