Two impressions:
1) It’s not easy to get the coal, both underground (long wall), and surface (excavator, loader, truck). The geological condition (thinner seam) is making the job more difficult. One scene remains in my mind is miners eating lunch in the tunnel, while I was eating lunch in the office.
2) Commercial air travel is changed. No more spare capacity, and if affected by weather, the delay and cancellation will make travel less pleasant. We (travelers) are commodity anyway.
