Congratulations Mazzy,
You'll never forget your first solo - no matter how many flights you make afterwards.
On my first solo I remember climbing up from the runway, taking a deep breath and saying 'Well, its up to you to get this thing back down again!' On my downwind leg, I was told to orbit. Thinking about it much later, it ocurred to me that the controller was hedging his bets, by getting the inbound aircraft down before me in case I spread myself across the runway!
Hope that you enjoy the rest of your training and I look forward to reading about it - this thread is bringing back some pleasant memorys.
