I just witnessed this C-17 make three low passes over Nashville, Tennessee. I’ll try to find out more details about what was going on to share later.
UPDATE: This was a practice flight for a flyover that was scheduled for Tennesee’s gubenatorial inauguration this weekend. The event has been moved indoors because the weather forecast is predicting snow and freezing rain. The Air National Guard already had the flight scheduled and decided to proceed with the practice flight.
