Media And Airplanes

This image is by far the most explanatory. It has its primary element, the fire and smoke, which on its own tells us something bad is happening. Then we have the secondary element, which tells us that passengers of something are dead, which gives us clues that it's probably a plane crash, and finally, the tertiary element, on the bottom, tell us that action is being taken regarding the situation in the image.

The next image is a screenshot from a video that was widely circulated by the media after a plane crash in Taipei. This one tells us that a plane is flying extremely close to the ground as a primary element, while the secondary element, the buildings in the background, tell us that this is close to a city, we don't know for a fact that the plane is crashing, or where this is, or much else about what's going on, besides that a plane is sideways and flying over a street.

This final photo is the least explanatory. It has only one element, the plane, and doesn't even tell us what the plane is doing. It could be taking off, it could be landing. We know it's a Germanwings plane, but beyond that, we know basically nothing about it, who's on it, what it's doing, or if there's anything special about it.
