Round windows manage pressure better, distributing stress evenly for safer flights. Square windows on early planes were replaced due to stress causing crashes. Aircraft windows have multiple ...

Airplane windows have a distinctive rounded-oval shape, unlike those found elsewhere. Why this design? It boils down to safety, physics, and engineering.

The primary reason for round windows lies in how pressure is distributed across an airplane’s fuselage. At cruising altitudes—typically 30,000 to 40,000 feet—commercial planes maintain a ...

An curved arrow pointing right. It seems like every single airplane window is round. How come they're not square-ish like most windows at home? The reason, according to the FAA, is for your own ...
