Most travelers never notice this clever airport design that helps keep thousands of flights safe every day, and it involves windows

Air traffic control tower windows are uniquely designed to slope inward, effectively minimizing distracting reflections from the interior. This innovative structure allows air traffic controllers to maintain unobstructed views of the surrounding skies. Additionally, the angled glass casts light reflections onto the dark ceiling, enhances aerodynamics, and lowers wind resistance, while specialized solar shading systems aid in glare mitigation and overall maintenance.
