Practice Relating to Rule 29. Medical Transports
Section B. Respect for and protection of medical aircraft
Mexico’s Army and Air Force Manual (2009), in a section on the 1949 Geneva Convention II, states:
Medical aircraft exclusively employed for the removal of the wounded, sick and shipwrecked and for the transport of medical supplies must be respected by the parties to the conflict, while flying at heights, at times and on routes specifically agreed upon between the parties to the conflict. Unless agreed otherwise, flights over enemy or enemy-occupied territory are prohibited.
