I am back from SIN/SYD flight. Everything OK but, I had problem at imigration desk in SYD. I had to explain why I fly to SYD only for a few hours. I showed them pictures in my camera and Ipad that I am a planespotter. Three times I explained everything about this MR. More than 30 min. In the end I promised that I will come to longer time next time :-).
