Why don't we see the glow of jet engines at night
Some technology here.
Much documentation about the inner workings tell that the operating temperature inside jet aircraft engines is about 1900 C, hotter than molten steel, which appears bright yellow hot.
Passengers sitting in the very front can peep into the front of the engines and in the very rear into the back of the engines, so one would expect to see reddish / orangish incandescense due to an indirect view to the combustion chamber of the engine. Unlike a car engine, a jet engine is more 'open'.
But during a night flight not any glow is seen, even not indirectly.
Why is that ?
