Just checked my log book - 15hrs 10 minutes. At Luton, students were not allowed to solo so at the time we had to fly to Bourn (35-40 minutes each way). That was where most of my dual solo flying took place too. If I take those trips off, it comes down to somewhere around 11-12 hours.
Like most people I remember my first solo like it was yesterday including the moron in the microlight who appeared from the left in front of me on short final (200 feet). The instructor would not let me have a chat to him when I eventually landed. Probably just a well as I dont think I would have wanted to discuss landing technique with him !!
What interesting things happened to others on their first solo ?
