I'm wondering if there's anything that explains the corkscrew movement described in the audio?
First, it's important to understand something fundamental about our brains
It's a fact of neuroscience that everything we experience is actually a figment of our imagination. Although our sensations feel accurate and truthful, they do not necessarily reproduce the physical reality of the outside world. Of course, many experiences in daily life reflect the physical stimuli that enter the brain. But the same neural machinery that interprets actual sensory inputs is also responsible for our dreams, delusions and failings of memory.

Many of these well known cognitive processes can produce certain perceptual illusions consistent with the stimuli the pilot and others were viewing. For example:
When light hits our retinas, it triggers a complex cascade of neural activity. Our visual cortex goes into overdrive, analyzing shapes, colors, and spatial relationships. But here's the kicker: our brains don't just passively receive this information, they're active participants in the interpretation game, filling in gaps and making assumptions based on past experiences and expectations. [eg availability heuristics, priming, confirmation bias]
This is where depth perception and spatial awareness come into play. Our brains use a variety of cues to determine the size and distance of objects in our environment. These include binocular disparity (the slight difference in images received by each eye), motion parallax (how objects appear to move relative to each other as we move), and even the texture and shading of surfaces. […]
Take the size-distance bias, for example. We tend to assume that larger objects are closer and smaller objects are farther away.

Also relating to vision at night with ambiguous lights, Gestalt cognitive organizational principles explain why people misinterpret separate or ambiguous stimuli as connected. For example, the laws of proximity, closure, similarity, and continuity are well known perceptual principles that enable the brain to process complex stimuli in general. They are heuristics the brain uses all the time but can create illusions/misperceptions. https://www.simplypsychology.org/what-is-gestalt-psychology.html#Gestalt-principles
Another relevant illusion
Autokinetic Effect: In dark environments with no frame of reference, a single stationary light can appear to move and heightened focus cause the light to appear erratic or shifting.
As was pointed out further up, the pilot acknowledges they were under a heightened state of emotional arousal/stress due to a heavy workload in the cockpit. Research has shown that stress can affect various aspects of visual processing, including:
1. Visual attention: Stress can narrow our focus, causing us to overlook peripheral information or become fixated on specific details.
2. Depth perception: High-stress situations may alter our ability to accurately judge distances or spatial relationships.
3. Color perception: Stress can influence how we perceive colors, potentially leading to changes in color intensity or even color distortions.
4. Motion perception: Stressful environments may affect our ability to track moving objects or accurately perceive speed and direction.

These are just some of the ways it's likely the pilot might have experienced completely normal and expected visual illusions. Small lights at night, priming for UFOs given the current drone flap, stressful conditions in the cabin, etc all increase the likelihood. Most people are completely unaware of how the brain works, and all of the ways in which it is constantly constructing reality in our mind that doesn't correlate to the external world. We don't see the world as it is, we see particular stimuli that our neurons have evolved to transduce into impulses and then process through a complex neural and cognitive architectural system. Without a good video of the "corkscrew" specifically, it's very likely, the above illusions could explain that phenomenon.
