Last night I witnessed a 737 taxiing out from the ramp with a very visible red glow from the turbine exhaust nozzle on the #2 engine. I've never witnessed that before or heard of it occurring.
I made a mental note of the tail number and flight number in the rare chance that I witnessed something dangerous, but by now its clear that there was nothing wrong.
My assumption is that something in the engine was at a much higher temperature than would be typical and was glowing red hot. Anybody have an explanation for what I witnessed?
Sounds like you were witnessing the actual combustion. Sounds like the light/conditions were just right.
On older Lear 23/24/25 and lots of straight turbo jets you can see it really well at night, especially on take off.
