I am on the fence I wasn't there but I notice some people say fake and hoax quite quickly and I don't feel as if time enough has been given to some of these pictures.
I don't think every single picture is fake myself but I know I would put these three letters in front of what I said if I wasn't totally sure (IMO)
Sound is a vibration that travels through an elastic medium as a wave. The speed of sound describes how much distance such a wave travels in a given amount of time. In dry air, at a temperature of 21 °C (70 °F) the speed of sound is 344 m/s (1238 km/h, or 769 mph, or 1128 ft/s).
