In a recent story for NBC, reporter Elisha Fieldstadt wrote about a passenger who reclined her seat on board an American Airlines flight which led to the man behind her repeatedly punching her seat. 
Fieldstadt used the inverted pyramid story structure in her article. The article begins with the most basic facts and adds more detail with each paragraph. 
The first source she refers to is the woman who reclined her seat and posted a video of the incident on twitter. This makes sense as she is the "main character" of the story. 
A few paragraphs later, Fieldstadt sites American Airlines and how they are handling the situation. 
The last source she used was people reacting on twitter and what they had to say about the incident. 
This story is very straight forward and would not require a more complicated structure to convey the information.
