Explain the meaning, scope and sources of international air and space law.

International air law = the international law of the airspace and civil aviation — the rules governing the state's sovereignty column above its territory, the aircraft's nationality and registration, the navigation's exchange (the air service agreements), the carrier's liability, and the offences against aviation (the hijacking-and-sabotage family). The law of outer space = the international law of the space beyond the airspace — the exploration-and-use regime (the province-of-all-mankind), the space objects' registration, the damage's liability, and the astronauts' rescue. The two regimes' foundation-contrast (the course's first lesson): the airspace = sovereignty (the state's column); the outer space = freedom (the non-appropriation) — Unit 7's table. The sources (the combined list): (i) the treaties — the Chicago Convention 1944 (the aviation's constitution) + the liability-and-security conventions (Warsaw-Montreal; Tokyo-Hague- Montreal) and the five UN space treaties (the OST 1967 + the four); (ii) the custom (the sovereignty's pre-treaty life; the SARPs' practice); (iii) the ICAO's standards-and- recommended-practices (SARPs) — the Annexes' technical law (the Chicago Article 37 machinery: the quasi-legislative adoption the states notify-or-file-differences against); (iv) the bilateral air service agreements (the traffic rights' contractual world — 1.5); (v) the General Assembly's principles (the space law's soft-law classics); (vi) the national legislation (the Civil Aviation Act 2053; the space powers' licensing statutes); (vii) the judicial-and-arbitral decisions (the liability-and-dispute jurisprudence).
