Congratulations!! =)
A student at the School where I studied did his first solo in a DA20 Katana with the registration no SE-LYB. He took off on runway 19 and at 400 ft his engine died... He did a turn and landed on the horse racing circuit just south of the airport.
I can promise you that he's never going to forget that day... He finished his PPL but I havn't after that...
My first solo was the best day of my life, I took off on RWY 19 ESGP in a brand new DA40 TDI named SE-LYA. Just as I took off and selected Flaps Up i sort of screamed WOOOW =) I did 2 touch and goes, then ended up in a holding while RyanAir was making a landing. In total there were 5 aircraft in the air waiting to land, I was no 5. My first solo with a total of 2 touch and goes and 1 landing lasted for about 1 hour... =)
