I saw nothing on Marinetraffic for EIII today or yesterday when the three ships were splashing around the harbor. Kinda odd considering Marinetraffic has a receiver bolted to Fishlips. I only see one current hit and no path / track from EIII on Vesselfinder. Is anyone seeing better with the other services?

What would have been even more interesting in 360deg would be the sight of the safing crew coming aboard and doing their thing.
Go Quest heading out to sea:http://www.marinetraffic.com/en/ais/details/ships/shipid:450521/mmsi:367564890/imo:1155515/vessel:GO_QUESTEdit: Same for Go Searcherhttp://www.marinetraffic.com/en/ais/details/ships/shipid:426008/mmsi:366584000/imo:9591648/vessel:GO_SEARCHER
if both Go sisters are going does that mean fairing recovery work?
What is the yellow apparatus at the starboard rear of OCISLY? Seems like it has two vertical bars in back, a cylinder inside, and perhaps a ladder on the deck side? It seems to be overhanging the stern slightly.
I noticed that thing too, I think it may be new. Got good screen shots of it, but don't think I can post them for IP reasons. On the other hand, it is not an angle we usually see Ocisly from.Matthew
And since this was a topic elsewhere - no sonic boom in the video... Obvious why, but still cool.

Did you watch the same video? Check your volume maybe There's ambient noise from the gensets, then three quick pops immediately followed by rocket sounds that persist until cutoff. The mic on this setup lacks sufficient dynamic range, so the boom and thrust sounds don't sound much louder than the ambient noise on the recording. I'm sure it's quite different in person I can believe there being three pops at minimum range... During Orbcomm I heard two from State Road 3, and Jim heard 1 from wherever he was.

Just to play devil's advocate, though: all the "with fairing" missions have been GTO attempts, right? It's *possible* that the second Go * ship is there for some other GTO-related reason, maybe even just downrange distance, say. We'll really get confirmation if we see it going out for a LEO-with-fairing mission... or if it comes back with bits of fairing on deck.
Rewatching my landing video, I remembered wrong, it was also 3 pops in about the same cadence as this new video.Here's how the Orbcomm landing's sonic boom was modeled; obviously the boom for an ASDS landing could be different for any number of reasons, but I'd say there's no chance of there not being a boom at ground zero.

So as I remembered (see picture), a sonic boom is only heard behind the vehicle, along a cone whose angle depends on the speed of the vehicle (and the speed of sound). So for every speed you get a different angle, but it's always backwards of the vehicle.
