Jan 10th is what my very (very) old logbook has as my first supervised solo. I consider that then and now when you are a pilot. You are by yourself, no one to tell you how to or if to correct it is your responsibility you are PIC (pilot in command).
Today Jan 10th was my 25th anniversary of that day for me. I was able to take my family flying to celebrate it, how lucky am I? To do what I enjoy and share it with others.
