I don't think that Evergreen was on a UN charter, I believe it was for Mercy Corps and US NGOs, not the UN.. .. .As for details of what is and isn't permitted, the airspace procedures and state of airfields currently in use are posted on <a href="http://www.unjlc.org/" target="_blank">www.unjlc.org/</a> . .. .According to the aviation bulletins which are also on the site, it seems that the authors are after operational info to pass on to all operators if you guys flying there have any extra information to offer.
