MINOR
The changes between the Introduced and Engrossed versions of HR 5174 are overwhelmingly formatting and typographic adjustments made during the engrossment process, including reflowing of line breaks, indentation normalization, and consolidation of multi-line entries into single lines. The one substantive policy change is in the Office of Spaceports provision (section 51501), where a relative date reference ('the date of enactment of this section') was replaced with the specific calendar date 'October 5, 2018,' fixing the effective date for that provision.
TIMELINE
In section 51501 (Office of Spaceports), the reference to 'the date of enactment of this section' was replaced with the specific date 'October 5, 2018,' establishing a fixed effective date rather than one tied to when the bill becomes law.
TECHNICAL
Throughout the bill, extensive formatting changes were made including reflowing of line breaks, indentation adjustments, consolidation of multi-line table-of-contents entries into single lines, and normalization of spacing. These are standard engrossment edits with no policy impact.
