 Once we get into the meat of the launch, we're departing one after another. Sure enough, as we're leaving around 2 a.m., the airport is buzzing with activity. Planes with brown UPS tails line up at nearly every gate and taxi around the runway. Worldport will be abuzz until around 5 a.m. when the final planes depart. On a clear night like tonight, you can see the aircraft with little white dots in the sky lined up coming in. And when they go out, it's literally one after another.
