>> oh, my goodness. >> it was just unbelievable to me. >> march 25th, 2011, dave darby is spending the afternoon at albert whitted airfield, a small airport just outside of tampa, florida. >> my buddy, kirk, who's been building this air control tower back here, he's been doing it for the past year and a half. i hadn't come out to check it out yet, so he wanted me to come and see it, so we decided to conveniently come and check it out the day the honda grand prix was going on. >> the honda grand prix is an open wheel indycar race and portions of the airport, including east-west runway, become part of the actual race course. >> the tower provides a perfect view to watch the race, so dave decides to bring his camera along. >> we were on top of the tower on the roof and i was just shooting just footage of, like, everything that was around, and then i noticed that there was a bunch of these old warplanes that were taxiing over here on
