There's A Reason Airplane Windows Are Never Square

The rounded shape isn't a design choice. It's a lifesaver.

Next time you fly, notice the windows. Every corner is gently curved. That is not for looks.

Sharp corners concentrate stress. At high altitude, with huge pressure differences, that stress finds the weak point.

Early aircraft learned this the hard way. Engineers switched to rounded windows to spread the load evenly.

So that soft oval shape by your seat is quietly one of the smartest safety decisions in the sky.
