All right... NIMBYs.
GSO expanded and built the news passenger terminal in 1983 I think. Bank when Wrangler Aviation had the huge Canadair cargo flights there, before the switch to the a300s and the L10-11 of Tradewinds.
Anyhow. Back then, all that was around the airport was farms and a small development of houses around the Guilford College area of Greensboro. Soon after, in the mid to late 80s, High Point expanded North and Greensboro West, towards the airport. Built subdivisions, and apartment complexes. And what is messed up, is they are STILL building apartments right under the usual landing path of freight and cargo ops into the airport. So YES, it is a bunch of people who got a good deal on property and housing because it is near the airport, and its mainly. When simple research could have prevented such bad decisions. And it seems to be bad planning on the Plannign boards of both cities that allowed this to happen.
