I have a specific question about one technical issue that Bob Lazar brought up in an interview, and I’m trying to find older sources

I’m sure there are people very familiar with this topic, and perhaps you can help me. In an interview on JRE #1315 Bob Lazar makes a specific claim regarding UAPs rotating into the direction of intended travel, and says that it’s how they operate. He says he learned this in the late 80s during his experience studying their gravity-based propulsion systems: https://www.youtube.com/watch?v=BEWz4SXfyCQ&t=1h29m20s

“The way the craft that we worked on flies is it doesn’t fly like a conventional aircraft does, and it doesn’t fly like a flying saucer would in a 1950’s movie. It flies belly first. I mean, it may set down conventionally but it always rotates. It does a roll maneuver, puts its belly towards the target, and then moves away at high speed.”

During this part of the conversation they’re referencing the video referred to as “GIMBAL,” which shows an apparently rotating UAP a pilot and his WSO captured in 2015 on an ATFLIR pod on their F/A-18, and released by the Pentagon in 2020.

I’m looking for any reference Lazar made prior to the release of the “GIMBAL” video that duplicates his claim that UAPs maneuver by rotating.

As I think “GIMBAL” is the first public video about it, him having made this claim prior to its release would be very strong corroborating evidence that he is credible and has private knowledge. It would strengthen his argument considerably. Similarly, if he only said this after it’s publicly known (despite it being one of the things he says he knew from his time on a secret UAP propulsion project) and isn’t disclosing that fact, it would cast more doubt on his story.
