We are now with Ott DeFoe just about a half mile away. He's set up on a ledge with multiple brushpiles marked. One keeper so far. This is the area where the greater part of the Space Shuttle debris crashed into the lake a few years back. Dennis Tietje was on the lake that day, farther to the north where the sky was clear. He saw a brilliant light break the horizon and knew it was the shuttle. It then took a 45-degree turn and he knew something was wrong. "It started looking like a fighter plane shooting rockets toward the lake. I knew that it was breaking up. It rained debris for a long time; the sky was full of smoke."
