What viewing advantage occurs when a KSC launch heads east over the Atlantic Ocean?

Viewers get a full, unobstructed view of the ascent, and sound arrives relatively unimpeded across the water.

The launch azimuth, or the direction of travel after clearing the tower, profoundly affects the viewing experience. Since most launches from KSC are directed eastward over the Atlantic Ocean, observers benefit from a long, clear path above the water. This geography ensures an unobstructed visual panorama of the rocket ascending into the sky. Furthermore, sound transmission over water tends to be less scattered or absorbed by ground structures and terrain, allowing the acoustic signature of the launch to reach spectators across the water relatively unimpeded, contributing to the full sensory experience.
