My buddy Dan had some work done to the turbo on his Bonanza and needed a lift to KHVC, Hopkinsville Kentucky to pickup his plane. It was a nice flight out there despite the brisk 30kt headwinds, which were quickly forgiven due to the return flight's 35kt tail winds :)
Dan took off and I observed from my plane mid-field to make sure no smoke or oil issues, he did a fly by and then I joined up with him in a close formation as I observed for any problems. No issues, so we continued on home. It was fun getting in a little formation work as I havent done it in a while.
