A spaceport need not be open to the public
What the document says“A facility shall not be required to be available for use by the general public to be treated as a spaceport for purposes of this section.”
The section provides that a facility need not be open to the general public to count as a spaceport, and that the bar in subsection (c)(2)(E) on manufacturing facilities and industrial parks does not apply to spaceport property used for making, assembling or repairing spacecraft and related items.
What the document actually says“A facility shall not be required to be available for use by the general public to be treated as a spaceport for purposes of this section.”
A site need not be open to the public. It still counts as a spaceport.
Airports are usually open to all. Spaceports are not held to that. A bar on factories also does not apply here.
No action is recorded against this proposal. That is not evidence that none has been taken, and nobody has yet read it against the record. See what the tracker does not yet cover.
