My first solo sticks in my mind, and having tower yell at me for being above pattern altitude, cause I was busy watching the FedEx 727 land. (Gotta know where that wake turbulence ends right!?)
Then like 2 semesters later I remember driving away from the airport thinking about my crazy life. My 8:00 class was my flight lab then I had a 10:30 French class, that kinda made me giggle all semester.
I still think my first student's solo is the most memorable. I did then and had up until I read this thread stand on the ramp and watch. I kinda like the idea of going inside where it's warm, cause like you said, "ain't bugger you can do anyways." Never thought about that one!
