Hangar 1 Historic American Engineering Record (HAER) Report

A Historic American Engineering Record was developed for Hangar 1 in order to capture the History and Context of the structure prior to any action being taken that could compromise the integrity of the building. HAER documentation level one was used for the Hangar 1 HAER.

Along with the American Society of Civil Engineers, and the Library of Congress, the National Park Service established HAER in 1969 to document historic sites and structures related to engineering and industry. The HEAR collections document achievements in architecture, engineering, and design in the United States and its territories through a comprehensive range of building types and engineering technologies.

This page will feature an electronic version of the Historic American Engineering Record (HAER) that was developed for Hangar 1.

*Note: There are differing opinions about the correct way to reference the name of this hangar. The original architectural drawings refer to the structure as "Hangar No. 1" but, for decades, this hangar has been widely referred to as both "Hangar 1" and "Hangar One." Because a definitive way of presenting the name of the structure has not emerged, references to it vary in the documentation available here.
