If you watch the video that is just to the right of the article you will see what was broadcast on the 10 PM newscast that I saw live last night. Even though the original article that was published soon after the accident (around 6 PM local time) correctly states that it was a ground power unit, the 10 PM news reports that the Dash hit a baggage cart. Obviously the news had the correct information but likely just decided not to use GPU since the majority of the general public might not know what that is.
Let this be a lesson that the news media often distorts truth. Albeit minor in this case, they still had the facts and decided to report false information. You really have to take what these clowns say worth a grain of salt.
