Frank is easy to find on Tuesday. He's at JFK at 7am sharp, not in the terminal, they don't let him in; he's out in the parking lot, rain or shine, with a stopwatch and a clip-board, rating the big jets. He's timing the big birds, timing take-offs and landings, counting planes, studying, deleting what he knows happened with facts: 737 is the workhorse of the fleet, safest bird flying.
