I had noticed the other night - to my guildies - that there didn't appear to be but one flight point on Sholazar Basin. Turns out I was wrong.
The 2nd flight point appears once you help out with a quest line that start with [Need an engine, take an engine]. The 2nd quest of that line concludes it, at which point a flight master in a biplane appears.
While no big deal in the great scheme of things, it's a nice detail. Well done, Blizz.
