2nd stage burn was visible from the 1st stage feed. Usual black out at separation for a classified payload. SpaceX confirmed good fairing deploy.

Screen shots of Zuma vs CRS-13. You can see the 2nd stage plume in both shots from Zuma. CRS-13 shows the relation between 1st and 2nd stage at the same point in flight (1st stage boost back 2nd stage boost to orbit).

thanks... the second frame grab is right before second stage when dark ( it never did burn, just a dull reddish glow for about 10 seconds ) Also, sound reverberations were very short, only about 40% of normal time.

Interesting. Military payload, might've been using a different chemistry in the engine from the typical commercial payloads. Also might've been a low-orbiting satellite, maybe below even ISS, which would mean it wouldn't require as much energy to move to orbit.
