Point 3 goes against normal behavior of hot metals, which emit infrared or visible light as they get hotter. It's called black-body radiation, and it's why iron and steel glow in a blacksmith forge.
The "moving parts" may be due to heat waves moving through the air (see also: mirage at a distance)

People refer to it as 'transparent' because it begins to glow the same color as the jet plume under afterburner use. https://gizmodo.com/this-is-an-image-of-the-very-last-test-of-the-pratt-w-1484943138 https://gizmodo.com/this-is-an-image-of-the-very-last-test-o...
