Maybe the "three days" part is a "red herring," in other words, just an error.
Here are some comments from one of the participants:

The thing I find disturbing is that they did not stay together. Essentially, at that point, you have first timers going
solo up Skyline. This seems like a
really bad idea, and it seems grossly irresponsible. If the gentleman who was choppered out had passed out, fallen, etc, no one would be there to see him. And, as the comments of the writer on the above link show, at least one of the first timers did get lost -- more than once. OK, so I'm going to say something critical here, but I think leaving a first timer on the trail constitutes abandonment. I think that's just short of criminal. I can't imagine ever leaving someone to fend for himself out in the sun on a harsh, ill defined route short of immediate threat to my own life or the lives of others. I hope this isn't too strong of a statement, but this is one of the most horrifying things I've heard of with respect to hiking in a very long time. I hope there's something I'm not aware of here, but absent that, I stongly condemn the actions of the leader. I hope the leader's actions were due to a lack of experience and not a cavalier attitude towards human life.
