WebFeb 13, 2024 · An airplane flying over the ground can still be visible to a radar if its height is higher than a certain value. But below the "line of sight" of the radar, the Earth's curvature would effectively hide it. That area is known as the shadow zone. A similar concept applies to our sight, too: discover it with our Earth curvature calculator! Web“I recorded a 23 minute and 45 seconds time-lapse, which by those measurements means the plane traveled a little over 203 miles. According to curvature math given to explain the globe model, this should have resulted in the compensation of 5 miles of curvature. As you’ll see there was no measurable compensation for curvature,” he said.
