🇺🇸 Philadelphia, United States of America
Philadelphia is one of the largest population centres on Earth. Real-Earth coordinates 39.946°, -75.180°, population 5,492,000. Skyline in every direction and an approach that never quite ends — one of the more demanding places to fly low and fast. Skydex flies the real Earth here — the elevation, coastline and city layout under the aircraft come from the same data the map does, and the sky is shared with everyone else flying it.
