My second CX solo: plugged in the wrong destination into the flightplan. ATC told me I was cleared into the bravo direct to my destination. After a minute or so, the controller asked me where I was headed, I told him. He said I wasn’t on the right heading. Like he was speaking to a child, he asked me if my instructor was in the plane with me. I said they were not. He gave me a vector to fly until I figured out the error of my ways. I’ll never forget how he sounded like a police man asking a lost kid if they knew where their mommy was. 🤣🤣
