It is an image of an aircraft passing through an area of high atmospheric moisture. The high pressure wave created by the aircraft is enough to condense the ambiant moisture to form a temporary cloud. Once the aircraft passes, the cloud returns to its previous state, which appears as if nothing is there. An aircraft breaking the soundbarrier would have no external visual effects. To watch the event would be boring. Visual effects = no. Physical effects = yes. The cloud effect can be done at practilly any speed. Depends of the moisture percent of the ambiant air. I have seen this on propeller dirven aircraft, and helecopters as well. This NOT an image of an aircraft breaking the sonic barrier.

It really does happen with aircraft traveling at high speeds. Here's how it happens: The leading edges of the aircraft compress the air significantly when they are traveling at speeds in excess of Mach .95(ish). As the air passes the leading edge, it expands causing rapid cooling (same idea as when a CO2 cartridge pops a leak). If the cooled air is at or below the dew point, the cloud forms. The misnomer on this page is that this phenomenon occurs only above Mach 1. This can happen at speeds as low as Mach 0.75. I have seen it happen. Despite the misnomer and the science of it all, it still is pretty awesome seeing this happen. Go to an air show. It's very common. This isn’t fake.
