When I was last at Leicester, there were dozens of ties hanging on the walls around the bar. These seemed to be "first solo" ties and each one had the pilots name, first-solo, and the date written on the tie in white paint. At least it looked like paint. I thought it was a superb tradition (much better than being thrown in a fountain GR14). I wished they had done this at the club where I learnt to fly.
I assume you are expected to be formally dressed for your first solo at Leicester....
I'm hoping Mrs QNH will be doing her first solo before too long. I'm open to (polite) suggestions to help her celebrate the event.
