Drops just short of supersonic

As long as the pilots didn't see him, or worse, get
pictures of him, he'd be fine. There wasn't anything in
the air that could keep up with him.

He put on the speed before pulling up short. Other
planes were coming from several different directions.
While he'd be able to outdistance them easily, he
wasn't sure just how far their cameras could penetrate
the cloud cover.

Allowing himself to drop straight down, Clark fell
at a speed just short of supersonic.

By the time the planes broke cloud cover, he was
already on the ground and stepping into a building that
was warm and filled with sound. They wouldn't be
looking for a man, and even if they were, by the time
anyone attempted to catch up with him he'd be long
gone.
