These are the top aeronautics companies in Houston

Information on The List was obtained through Houston Business Journal research or supplied by individual firms through questionnaires that HBJ could not independently verify. In case of ties, firms are ranked alphabetically. Additionally, companies that did not respond to surveys but were still included on this year's List are sorted by estimated total employment figures derived from HBJ archives; annual filings with the U.S. Department of Labor; and other firm-specific resources. For information about this and other HBJ Lists, please contact Assistant Managing Editor Wyatt Loy at wloy@bizjournals.com.
