Watching the replay, that's what I'm thinking too.

No, something is torn away then you have a dark smoke near a corner (the top one on the video) during one second.

This article says the Orbcomm waits half an hour before the 2nd stage relights and takes it above ISS.

That's what I thought was going to happen all along. Why wasn't this reported clearly?  ???

I thought it might be a large chunk of ice breaking off and impacting the corner.  Seeing the replay, it does look like a pretty violent event.

Wow, that looked extremely violent, like a turbopump exploding. We may have just seen the first real test of engine out capability...

I'd bet on ice after watching closely, it has the look I remember from the shuttle - spray of particles then chunks.

I also thought that the first stage burned ~20 seconds longer than planned, but it might have been that the audio and video were out of sync.

An exploding turbopump could also explain that.

Doubtful. Probably the least likely explanation. If it had been, then MECO 2 would've been delayed.

Guesstimation at best. Better to wait for post flight briefing.

I think Gwynne just confirmed that, or something like it.   ;)

"Corner"? Something seems to disintegrate right at +1:20. MaxQ, "vehicle is supersonic" then poof. Looks too rough to be a shock ring type effect.

See attached (modestly enhanced and slowed down 30x, at full resolution).  Gwen just said there was an anomaly on engine one.

Anomaly and a longer burn was basically confirmed.  Implied engine out?

please note : this is not official, just a guess by the poster.
No mention whatsoever of a turbopump exploding on the presser.

Too much speculation until updates are announced.
