They built huge high power amplifiers and transducers for shake tables, and aircraft flutter testing. Flutter is a phenomenon which results when aeroelasticity sets up a positive feedback loop and an aircraft, whole or in some part (such as a movable control surface) oscillates in a greater and greater amplitude motion until it breaks itself apart. LTV was the successor to Vought and I think Republic as well. I know Republic Steel in Chicago became LTV Steel. Temco was a small aircraft manufacturer that built one underpowered trainer plane. Vought was the very successful manufacturer of WWII and Cold War fighter planes.

I believe Nancy Ling Perry was a member of the Ling family in question. She was an attractive but nutty radical killed in the SLA shootout in 1974. I believe one of the cops on the other end was Jim Dougherty, who was in the famous picture perp walking Patty Hearst-and also was the Dougherty (as) in Norma Jeane Dougherty, a then 16-year old he married to keep her out of the orphanage. Better known today as Marilyn Monroe.
