Hughes H-4 Hercules
The Hughes H-4 Hercules (commonly known as the ''Spruce Goose''; Aircraft registration, registration NX37602) is a prototype strategic airlift flying boat designed and built by the Hughes Aircraft Company. Intended as a transatlantic flight transport for use during World War II, it was not completed in time to be used in the war. The aircraft made only one brief flight, on November 2, 1947, and the project never advanced beyond the prototype. Built from wood (Duramold process) because of wartime restrictions on the use of aluminum and concerns about weight, the aircraft was nicknamed the ''Spruce Goose'' by critics, although it was made almost entirely of birch.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 49–58, Cypress, CA, 2013. .

H-4 Visa
An H-4 visa is a United States visa issued to dependent family members of H-1B, H-1B1, H-2A, H-2B, and H-3 visa holders to allow them to travel to the United States to accompany or reunite with the principal visa holder. A dependent family member is a spouse or unmarried child under the age of 21. If a dependent of an H-1B, H-1B1, H-2A, H-2B, or H-3 worker is already in the United States, they can apply for H-4 immigration status by filing Form I-539 for change of status with United States Citizenship and Immigration Services (USCIS). Family members may alternatively be admitted in other non-immigrant categories for which they qualify, such as the F-1 category for children or spouses who will be students or the H-1B category for a spouse whose employer has also obtained approval of an H-1B visa petition to employ the spouse. An H-4 visa holder is admitted to the U.S. for the duration of the primary (H-1B, H-1B1, H-2A, H-2B, or H-3) immigration status. A noncitizen with H-4 i ...
