This site uses two separate and distinctly different search engines.
The site search at the top of each main page searches articles, photos, videos, crew information pages, etc. The site search does not search the database. Use the site search to find general information that is not included in the database.
The database search in the database section of the website searches only database records. This database search engine uses powerful filters that allow you to narrow your search to a specific person, airplane, mission, crew, MACR, casualty report, etc. Use the database search to find specific and detailed records.
