re Air-Sea Rescue Aircraft and the Geneva Convention
from Geneva Convention 1929
Article 7
___The protection to which medical formations and establishments are entitled shall cease if they are made use of to commit acts harmful to the enemy.
Article 18
___Medical aircraft, that is to say, aircraft exclusively employed for the removal of wounded and sick and for the transport of medical personnel and equipment, shall not be attacked, but shall be respected by the belligerents, while flying at heights, times and on routes specifically agreed upon between the belligerents concerned.*
___They shall bear, clearly marked, the distinctive emblem prescribed in Article 38, together with their national colours, on their lower, upper and lateral surfaces. They shall be provided with any other markings or means of identification that may be agreed upon between the belligerents upon the outbreak or during the course of hostilities.
___Unless agreed otherwise, flights over enemy or enemy-occupied territory are prohibited.
___Medical aircraft shall obey every summons to land. In the event of a landing thus imposed, the aircraft with its occupants may continue its flight after examination, if any.
___In the event of an involuntary landing in enemy or enemy-occupied territory, the wounded and sick, as well as the crew of the aircraft shall be prisoners of war. The medical personnel shall be treated according to Article 24 and the Articles following.
(My note: There was an attempt (before and during the 1929 Convention) to expand and provide more detailed protections for medical aircraft and aircraft searching for wounded or downed aircraft crew in need of rescue, but no significant changes were made. Although I am sure that the information is out there somewhere, I could not find a record of the suggested changes or discussions.)
from Geneva Convention 1949
[Excerpt from Article 36]
Paragraph 1 - Definition and Protection
___Medical aircraft have the same role under the 1949 Convention as in the past: flying alone or in convoys, they may be used both for the evacuation of the wounded and sick, and for transporting medical personnel and material. Like any other means of transport, they may be the property of the army, or of voluntary aid societies, or have been requisitioned.
___As in 1929, it was not considered possible, for reasons of military security, to accord protection to aircraft searching for wounded.*
___The nature of the protection accorded remains the same: the aircraft, like medical transport on land, are placed on the same footing as mobile medical units.
(My note: There is still no protection included in the Geneva Convention for the search and rescue aircraft, only for the personnel on board after it is shot down. The protections afforded the occupants are as for other military or civilian aircrew, medical personnel, wounded, etc.)
