In How High the Sky?, jurist Thomas Gangale explores the oldest and most important controversy in space law: how far up does national airspace go, and where does the international environment of outer space begin? Even though nations did not object to the first satellites flying over their sovereign territory, after more than six decades there is still no international agreement on how low the right of space object overflight extends, nor are there agreed legal definitions of “space object” and “space activity.” Dr. Gangale brings his background as an aerospace engineer to bear in exploding long-held beliefs of the legal community, and he offers a draft international convention to settle the oldest and most intractable problems in space law.
