The Graveyard Spiral

There's a possible explanation for the light. The aircraft is trying to correct what the pilot sees as its orientation in space, and they start banking. This could explain the eyewitness accounts too. When I think about reporting about lights that I feel are a thousand feet above me in a plane, I don't think about this Venus, Mars, Mercury, and Antares,. A very bright star. Super bright, but also stars. Very far away.
