Hello, aircraft lovers! Have you ever thought why airplane windows are round instead of square like the ones on your house? And why do the shades have to be up when planes take off and land? Although its been around since the 1920s, commercial air travel didnt really take off until the 50s. Thats when airplanes started to fly at higher altitudes. It saved airlines tons of money because up there, the air is significantly less dense and aircraft use less fuel.
But the early, box-shaped planes couldnt handle that kind of pressure, so engineers presented a new cylinder-shaped cabin. And even after this upgrade, aircraft still had standard square windows, and that turned out to be a grave mistake Date: 2022-04-19
