The honest answer is: less than her admirers sometimes claim, and substantially more than the absence of public documentation might suggest.

What can be known includes the following, all of it documented:

She worked at Lockheed for thirty-one years in positions that required advanced mathematical and engineering skill.

She held a professional engineering license from the state of California.

She is listed as a co-author of the Planetary Flight Handbook, a serious technical document with real engineering content.

She worked in Lockheed’s advanced development environment during the period when that environment was producing some of the most technically demanding aerospace work in American history.

She was recognized by colleagues as a substantive contributor to the work of her team.
