Tr-3b
>the object appeared to be an equilateral triangle, with a white light at each vertex and a faint blue glow beneath its base. It's not unidentified, it's the low tech type space craft that America uses to haul cargo or troops. It is also not an equalatural triangle, the angle is similar to an arrow head. The glow towards the middle is the main engine, and the 3 outer lights are smaller motors, used to steer the craft. When the craft is used fo troops, it can haul about 150 to 200. All American spacecraft are required to not exceed 20k mph inside Earth's atmosphere, just for safety. The original model, the TR-3B, was built in the 1970's and there have been new models since then. Art Bell used to talk about the TR-3B. . https://patentimages.storage.googleapis.com/31/45/3f/583bc0d7058997/US20060145019A1.pdf
