About 10 minutes ago we had a C17 fly right over our house. I thought it was extremely low, roughly 500-1000 feet in altitude. It damn near shook our house.

I went on flightradarx.com, and was able to locate the exact plane. It shows the altitude at 825 feet. In my time in this area, I've never seen or heard a plane come so low by our neighborhood.

I'm not saying this is some habbening or that it's overly exciting, I'm just curious to know if anyone would have information as to why they might be flying so low? How common is this? Any insight at all would be appreciated.
