As pilots Stern and Koukkari look on helplessly, the mechanics, Jim Lauria and Roby Bybee, go to work diagnosing the problem. We had a small window of time to get to Midland before dark. Would the flight be cancelled? It was a doohicky that was causing the light to go on in the thing-a-ma-jig! With knowledge and skills obviously beyond my comprehension, Roby and Jim fixed the problem and we were back in business, without a minute to spare. Pilots fly an airplane, but mechanics keep it in the air.
