With our altitude much higher now, it was time to start pulling some very heavy G's, and here is where the experience became out of this world. From that point forward, I have no clear recollection of the maneuvers we did—just the memories of flexing hard, breathing and fighting for consciousness. While looking down, I briefly saw what I believed to be the Homestead-Miami Speedway. What seemed like an eternity later, I thought I was driving a car on the racetrack below us. I hadn’t passed out, but I lost vision and had a complete “gray-out.” Once Scott unloaded the G's, I came to and was a bit confused, but I realized I was still in the jet and not on the ground racing a car on the track. It turned out that we were not even over the race track during those maneuvers.
