@Madussa , I just ran across this thread by chance. I don't know if you'll ever see this.
My late daddy used to fly a little Cessna similar to the one your dad was flying. I'm so sorry for your loss. I wasn't able to see the reports above (the links have expired), but I'm guessing his medicals were not up to date. My dad flew a lot after he was no longer supposed to due to a heart condition. He used to do some crazy things like "killing" the engine and flying as high as he could before the engine stalled. He was a great guy. I loved him so, so, so very much. No, he didn't die in a crash; he had cancer. Please use the inbox feature above and to the right to contact me if you ever want to chat.
