I could hide behind the adage that I don't write the headlines for the web (which is true), however I do for my newscast. In both cases, web and broadcast, there is a degree of salesmanship involved. If people aren't attracted to what you are writing/saying it doesn't matter how wonderful, detailed and epic the prose is that follows. That said, headlines must be accurate. While I like what you attempting in your example, it is too long. When whoever finalized the headline came up with "Disney’s new ‘Star Wars’ attraction evacuated on opening day, riders say" that was probably the most accurate thing we could have said at that time. We apparently added the sub headline "Disney World ride reportedly reopens about hour after being evacuated" as soon as that info came in.
God knows Disney and the other parks are usually.... let's call it "measured"... when talking on the record about any problems, if they comment at all, but their top people are quite quick to email or call us up if they are unhappy with something we've said or written. While it is extremely rare for us to make changes just because they are unhappy, sometimes we will try to find a compromise. Usually that means adding their response. None of us are perfect.
