01

In the 1950s, airplanes were built with square windows, which later caused serious safety problems.

Early Planes Had Square Windows

02

Sharp corners on square windows created weak points, which cracked under cabin pressure at high altitudes.

The Problem with Square Windows

03

The first jetliner, the de Havilland Comet, suffered fatal accidents due to square windows breaking in flight.

The Comet Disaster

04

Round windows distribute air pressure evenly, reducing stress points and preventing cracks.

Why Round is Safer

05

The smooth curves make round windows stronger, safer, and longer lasting for modern airplanes.

Stronger & Durable

06

Round windows also improve aesthetics, giving passengers a clearer, uninterrupted view of the skies.

Bonus: Passenger View
