Also how many planes are going the same direction at the same time? Atlanta is one of the busiest airports. So you’ve got one taking off for New York, then a few minutes later Chicago, a few minutes later, LAX, and then say Miami.
A few minutes? It’s more like 40 seconds. Sitting in a restaurant overlooking the runway having lunch as I awaited my flight, I tomed them taking off. And it was a double runway so sometimes 2 took off at the same time.
