It is the visible tip of an iceberg of technical knowledge and technical work that the classified nature of much of the rest of her work keeps mostly below the surface.

The Questions That Remain Open

There are things about Mary Ross’s career that the available record does not resolve.

The specific classified projects she worked on within Lockheed’s advanced development environment remain, so far as the public record shows, at least partially restricted.

The extent to which she contributed to specific missile designs, specific satellite programs, or specific aspects of the reconnaissance aircraft programs that the Skunk Works was known for is not established in available documentation.

The internal record of her career at Lockheed — the performance evaluations, the project assignments, the organizational structures she worked within — is not publicly available, if it has been preserved at all.
