Flying to get the Diamond TrianSoaring Award Oh oh
20 March 2015 | by ctyankee1See all my reviews

This episode is with Nancy and her female friend George. She is the piloting some sort of plane and she wants to get the Flying Diamond Award and George is her witness.

Ned their father's aide is driving a truck beneath them to transport the plane back once they finish the flight. During the process Nancy sees a car in an accident and tells Ned who reports to the police.

Ned reports it and is taken into custody because they do not believe him. The place where Nancy saw the car is said to have near a washed out bridge that has not been used for years. It is blocked so no car can cross. The police do not believe her or Ned.

Nancy does her own investigating. It gets very scary at times watching her and George climb around in the dark in the area of the washed out bridge.

Ned and Nancy investigate car information in the area where this happened. Nancy comes up with a very old popular car worth a lot of money and she believes that is what she saw. Through records an computer searches they find out answers to their question to help them solve the case. Lots of mystery and suspense.
