So why does the airport require items from factories that I have that still have 16 hours of building time before I can use them but the plane takes off in 14 hours? I have a perfect record with my airport send offs but now I'll lose that because I can't make ice cream and don't have cash to purchase the township cash to speed up the building. Seems like a huge flaw or obvious money grab for me to keep my record. Perhaps the build times should be shortened or the airport could better sense when the factories are actually useable.
