So I just found out about a Canadian woman who gave birth on an Air Canada flight on her way to Tokyo on mothers day. In this article: Ada Guan, B.C. woman who gave birth on plane, didn't know she was pregnant, it states,
...depending on where Chloe [the infant] was born along the route, she could be eligible for American citizenship if she was born above Hawaii in addition to Canadian citizenship
Is that really a thing? Does the USA grant citizenship to whomever is born in their airspace? The child has been given Canadian citizenship because the flight originated in Canada, but she was technically born at 35,000 ft somewhere over the pacific ocean (What's her birth certificate going to say? Place of Brith: 27.362444, -161.294046 at 35,000', or "International Waters"?) Would a child be eligible for a US passport if born in the stratosphere somewhere over Hawaii?
From discussion in Comments:
Either that flight took one heck of a detour, the reporter didn't get their facts straight, or Hawaii is in the Bering Sea.
