....and there I was thinking I was unique!
Cessna 210....total time in type...model...and local flying area....as long as it took to break ground...get the landing gear up...begin a turn...and start looking for the traffic ATC told me of....began to reduce power.....got a distinct shock when the engine started to die....immediately un-did what I had done....realized I had gotten the wrong knob. Still looking for the traffic....eased off on the power again....and realized from the sound of a dying engine....had done it all over again.
Third time I did the look...find...identify...grab...confirm....drill before moving anything! Very good thing I was alone.....hat size down quite a few down from breakfast.
