I can't speak for quail, but I do have hens and ducks and we live pretty close to a local runway. We get some WW2 harvards, and jet fighters taking off, and lots of small craft like Cesnas and large noisy helicoptors. For a start the hens were afraid, but they totally ignore them all now. Hopefully the same will go for your quail. Just make sure you have hiding places for them too.
