Spring 2019

 Picked up my new to me 1955 Cessna 180 from Mississippi, flew home with my dad as copilot, like a dog in a car his head was out the window the whole time. I bought this as a project to sell down the road but the focus will be to fly the 180 this summer and do the major work this winter.

 2019 summer News

  Bentley Air is looking foreword to many adventures this summer with the family and my 180 with plans to visit the Idaho back country to maybe a little 135 flying out of Seattle. You never know where one might end up when the prop is turning. I have a goal to get my CFIG this summer and do some more sailplane flying, this to me is one of the most enjoyable flying for the pure sense of flying and using the environment to travel. There is no place like cloud base.
