Since when has the FAA operated under the DOT?

Answer: C — 1967

The Federal Aviation Administration (FAA) began operating under the Department of Transportation (DOT) in 1967. This significant change was part of a government reorganization that aimed to consolidate various transportation-related functions into a single department, improving coordination and oversight. The FAA, which was established in 1958, was originally part of the Department of Commerce. This transition to the DOT marked a strategic shift in how air traffic and safety were managed in the United States, aligning aviation more closely with other modes of transportation. This context makes 1967 the correct answer as it reflects the historical timeline of the FAA's incorporation into a broader transportation framework within the government.
