Rounded windows: a safety choice born from disaster, physics, and decades of careful engineering at 40,000 feet.
Airplane windows are deliberately curved inward to counter cabin pressure, reducing stress on the fuselage and preventing cracks.
Ovals were chosen over circles in design because they distribute stress more evenly across materials, dramatically extending lifespans in aviation use.
Damage to an airplane window never causes immediate decompression due to multiple layers; pilots are trained to fly with a cracked pane while maintaining cabin pressure.
The iconic window shape hides a safety feature: rounded corners avoid stress concentration points that cause micro-cracks to propagate faster.
