I actually happened to hear, and get a short video of, a similar "roaring" sound a few months ago (April 20). And, by chance, I also happened to
find out what was causing it. There are two things I notice about these videos: first, it always seems to be cloudy, which would tend to reflect back
to the ground sounds that would otherwise dissipate in the air; and, second, the horizon isn't visible. Now, mind you, I haven't watched every video
out there, so I might be wrong that these are trends, but, of what I've seen, they seem to be a pattern I'm noticing.
The fact that you can't see the horizon is significant. What allowed me to determine the source of the sound I heard was the fact that I had a clear
view of the horizon.
