I think a little more context would be in order in this article.
For instance, why paper airplanes at all? What are they good for? How are they used and what is the essense of promotion by paper airplanes? What is the cultural context? What kind of event are they used at (for instance, for a certain age group)? Under which circumstances would they be useful (an example from some past event could be given)? Where does LibreOffice come into the picture (is the program used for producing the airplanes or is the program just promoted)? --Mortense (talk) 2013-08-03T18:45:44 (UTC)
