After taking a hike though the dense woods the other day, I came out into an open field, so I decided to have a look around and film with my GoPro. Only a moment after I started filming, I began hearing the sound of an airplane flying too low or something. I turned and looked, and I couldn't believe my eyes. It seems that I turned my GoPro up to look at the sky just in time to catch a view of the amazing sonic rainboom. I suppose I was as unexpectant of the shockwave as I was the pony, though.
