I finally finished the launch platform for my simulated Unha-3 inside Orbiter Space Flight Simulator.
I already did the flight testing (24 times since last night) and the first and second stages indeed fall where this map shows it will fall.
There was one time when the 2nd stage almost came within 100 kilometers of Legazpi City, but it was an error in my preprogrammed ascent guidance script that was the culprit. After fixing that, it followed the profile well.
So, I don't know about you, but I personally can sleep well now.
But for those curious enough, I'll release the video of the entire 5 minute 33 second flight of the Unha-3 (you didn't even know the ascent to orbit only lasts this long I bet?) with commentaries on what's happening and explaining where the expended stages will fall.
