Oh come on how can the "passenger" holding that bit of paper have endanged them? Its light hearted humour GRRRR makes me so mad some of this "news" we get now-a-days :(
A rogue seagull could've smashed its way through the cockpit, taking out the pilot! Then the guy with the paper would've been in danger of a 2 second delay whilst he dropped the paper. :p
On a more serious note, where in the article does it say anyone complained? I don't understand why it is news, as it has no actual informational purpose. Even the Daily Mail's article didn't have any negative comments, so why did they bother reporting it at all?? It almost seems like these news sources are trying to get people riled up...
