The Hague Rules of Air Warfare
The Hague, December, 1922-February, 1923

http://lawofwar.org/hague_rules_of_air_warfare.htm

Excerpts:

CHAPTER I-Applicability: Classification and Marks.

ARTICLE III
A military aircraft shall bear an external mark indicating its nation;
and military character.

[Note: There are no external markings on military shuttle missions
that indicate the military character of its missions (-the original
point in question-).]

A space shuttle is an 'aircraft' for relatively brief portions of its
mission, and then only for ascent-to-orbit and descent-from-orbit.

Its actual mission is carried out in space, where "Rules of Air Warfare"
and rules for "military aircraft" do not apply to a spacecraft.
