DJXL,
Don't mean to rain on your parade here but....
Playing around in the sim is good fun, especially at Kai Tak, the best part is that you can freeze the sim or start again if you crash.
In real life, however, I'd be crapping my pants trying to pull it off alone in a 747 with low vis. adding to the fun. I've flown into Kai Tak, and I wouldn't exactly call it pleasant....
As for a PPL landing a jetliner, I guess it's possible, but it sure as hell wouldn't be pretty. I'd say a 1% survival rate...
