The Burning Engines!!!
On some departures due to high power, you can see red glow as if the plane engines are on fire.
The glow is from the last stage turbine disc only visible from behind the engine under right lighting conditions.

Commercial jets use highratiobypass turbofans. The majority of the discharge flux is plain old atmospheric air driven by a huge and very powerful fan through an annular ducted cowling on the engine. That discharge is blown out of the cowl at speeds of a bit more than 500 mph.

I have mostly seen the engine glow from GE90 on Boeing 777 but in this video you can see it bright on Boeing 747 @ 01:06 and some from Airbus A380 @ 07:31

Enjoy the video of night Heavies departing low and bursting low clouds from Britain's busiest Airport London Heathrow.
