>> 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 100 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 up. >> 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 the runway and they were about to take off.
