She then went on to Indiana State for a Bachelors degree in Professional Aviation Flight Technology and finished all her training there. She has about 1500 hours of total time in various aircraft, predominately in Cessna 172s, Piper Warriors & Arrows. Jamyn has worked at Eagle Aircraft since 2001.  She was hired shortly after 9/11 and has been working there ever since. She did take a short jaunt to Alaska for about 3 years and moved back in 2006 coming straight back to Eagle Aircraft to instruct. She is most proud of the students she has taught and watching them grow in the field of aviation.  Some have moved on to airlines or corporate; while others just own airplanes and fly VFR to various places.  Her longtime goal in aviation is right where she is.  She loves teaching and having a family at the same time.  Since her husband has a crazy pilot schedule this is a way for her to continue to fly and have a good time doing it.
