the problem here is the lack of communication between defence officials and airlines inregards to eachothers procedures. I know at my airline we have procedures for such situations but as far as i know we have not been given information on the authorites procedures. granted every country has different procedures i assume or maybe under all jar or even icao members they keep to the same critera. then maybe we could brief the passengers more accuratly on what they are likely to encounter on the ground. if someone has been given this information from their please let us know then obviously its accesable
