Recently a UFO photographed over Phoenix was found to be a high flying NASA research balloon. This looks like something similar, but has nothing of the appearance of the NASA balloon. Could it be an amateur effort to create a UFO, or are research balloons becoming more common? It appears to morph into a rocket-like shape, complete with an exhaust glow. There is enough strangeness here to warrant a look.
