Silverad,
As a member of the working press for a quarter of a century, I can confirm that there is some truth that the media tend to bleed every little aspect of a story, sometime to ridiculous lengths.
But more often, the problem stems from reporters' ignorance, and I mean that in a nice way. They are often called upon to be an expert in organ transplantion one day, explosives the next, insect life the next, etc. etc. Most are generalists, particularly at smaller newspapers and television stations. It's tough to get up to speed on a complex issue in a single news cycle, before you have to move onto something else.
In this particular case, however, I question the editing. The statement that rocketry "contributed to the explosion" is bizarre, and should have been questioned by an editor. That's like saying economics contributed to the Depression. Weird.
