As ESPN would put it...Come on man!!! So you landed at an airport you were not endorsed to land in, you made a probable life altering decision, to say the least. You made the right call! Not to mention you even got you and the aircraft back ON TIME!!! Impressive.
You have made an excellent accomplishment, congratulation on your first of many X/C flights. We all know it is a different experience when you solo, but the first X/C there is nothing like it. Keep flying!
