        I’m not sure what you’re showing here. A comparison? The sheer number of planes at one time?

          Yeah. There’s a constant flow of planes. There’s a documentary I saw that talked about the weather after 9/11. Cloud cover and temp changed drastically during the few days when there were no flights.
