Congratulations. Brings back memories from many years ago. Strangely, I think I am one of the few people who didn't enjoy his first solo. It came completely unexpectedly after only 4hrs 20mins, following ATC gliding 17 years previously. It caught me by surprise, and I guess I wasn't psyched up for it. Fine after I'd turned finals tho', and I had no further problems. Enjoy the rest of your flying career.
