Actually, this isn't entirely true. If a birth occurred in transit or en route for example, the hospital could be listed as the location where the child was first examined. The certificate is supposed to contain a statement that the child was born en route, such as on a ship or on a plane, and nothing in the "letters of verification" precludes this from being possible.
That may be Kansas law but that’s not what Hawaii Public Health regulations state.
Chapter 8 Section 5 only requires that the certificate must be filed in the registration district where the child is first removed from the conveyance not that it is listed as the place of birth.
“When a birth, fetal death (stillborn), or death occurs in a moving conveyance, a birth, fetal death or death certificate as the case may be, shall be filed in the district which the child or remains were first removed from the conveyance”
Compare that to Kansas law:
“If a birth occurs on a moving conveyance, a birth certificate shall indicate as the place of birth the location where the child was first removed from the conveyance.”
See the difference in language.
