Interesting choice to build in Greensboro. That's also where Boom chose to build a factory and it looks massive as you leave the airport. The plan for this company's factory looks like it will be significantly larger.
The HondaJet HQ is here (and has been for some time), as well as a number of aircraft repair facilities inside the airport fence, and there are ~5mil people within a 90 minute drive of GSO, so it's becoming easier to source talent for aerospace as well.
Our long runways and the fact that we only have around ~7 flights arriving/departing per hour, and the proximity to Washington DC, is why GSO is used quite often for training operations for "Air Force One" - we see 28000 and 29000 do very low passes over our house around once a month as they do touch-and-go and go-around drills, so it's always funny to see the flurry of "did you guys see that?" posts on Nextdoor.
