Radiation-cooled nozzles often glow quite impressively. The first-stage

Ah, thanks.
Is it troubling that the heating on the Falcon nozzle appeared uneven?
Yeah, glowing hot spots are in the flow compression, cold spots are in a
shadow expansion. I thought it didn't look bad, but what does normal glow
look like?
Use the separation attitude, att rates, accel, jerk to move the second stage
engine to avoid the first. It looked like it could gimbal fast enough.
Don't mess with the lifetime (safety) of the engine.
