Launch forecast has updated and has worsened, now only 40% GO for the primary date, and 70% GO on the backup date.

Harbour tugs Florida and Eagle have arrived to help un-berth OCISLY. We are going to sea today!

Of Course i Still Love You has departed for the landing zone, roughly 28 km downrange!

SpaceX statement confirming OCISLY landing, and the possibility for sonic booms:

Since text in a JPEG image is not searchable or machine-readable, and since I couldn't find the text easily by searching Google, I just typed it in:

Quote from: SpaceX statement

HAWTHORNE, Calif. -- May 2, 2019. SpaceX is targeting Friday, May 3 for an instantaneous launch of its seventeenth Commercial Resupply Services mission (CRS-17) at 3:11 a.m. EDT, or 7:11 UTC, from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida.

Following stage separation, SpaceX will attempt to land Falcon 9's first stage on the company's "Of Course I Still Love You" droneship, which will be stationed approximately 12 miles off the coast of Cape Canaveral Air Force Station, Florida. The droneship will be operating within the flight keep out zone. Active boaters in the area should consult local advisories and security zones to ensure compliance. Prior to this mission, SpaceX has successfully landed 24 Falcon 9 first stages at sea using the company's autonomous droneships.

There is the possibility that residents of Brevard, Orange, Osceola, Indian River, Seminole, and Volusia counties may hear one or more sonic booms during the landing attempt. Residents of Brevard County are most likely to hear one or more sonic boom, although what residence experience will depend on weather conditions and other factors. A sonic boom is a brief thunder-like noise that a person on the ground hears when an aircraft or other vehicle flies overhead faster than the speed of sound.

SpaceX's launch webcast will go live approximately 15 minutes before Falcon 9's liftoff at spacex.com/webcast.

Whoops no sound:

Sounds back.

Kenny Todd (ISS Manager)

Closing parts of late load underway.

1,700 kg of cargo are onboard Dragon.

7 weeks left of increment 59. No issue getting this mission done during this crew's stay on issue.

Station is in good shape with successful MBSU replacement.

NASA and SpaceX worked to quickly and hard to determine that this cargo Dragon poses no additional risk to ISS based on Crew Dragon anomaly.

"No change to overall risk."

Hans -

SpaceX confirming that teams are working through analysis of Crew Dragon issue.
The facts so far:
- Power up happened fine.
- Dracos were fired in 2 sets for 5 seconds.
- Just before SuperDraco firing, anomaly occurred and vehicle was destroyed.

High amount of data was recorded. Too early to speculate on cause. Data indicates anomaly occurred during activation of SuperDraco. No reason at this point to believe there's an issue with SuperDraco themselves.

02:48 EDT (0648 UTC) is the launch time Saturday if we need the backup day.

Hopefully someone caught a screengrab of the Dragon wobble before being grabbed by Canadarm2.

OCO-3 (Orbital Carbon Observatory 3) and STP-H6 (Space Test Program - Houston 6) are the external cargo elements.
