I believe it's more likely IFA is in July now.

So it be. In-flight abort test slips to NET July according to Ben Cooper:

I feel better about the NET July 2019 date. This will hopefully allow time for telemetry analysis, a detailed capsule tear down to what ever level is deemed necessary and provide time for the associated paper work.

I still think that this is real quick considering crew will be on the following demonstration flight.

This has to be done right and the process appears to be progressing at a good pace for a Q4 2019 DM-2 mission.

Only Crew Dragon ? No Falcon FT ?

Anyone have any info on what kind of static fire was planned for today?

Also, the one pic shown is worrying IMHO; the color of that cloud looks rather like what I've seen from destroyed hypergolic stages (such as video of the Proton launch with the upside-down sensor).

No falcon involved here, just Crew Dragon. They have a test stand south of the LZ-1 landing pad for static fires of SuperDracos.

Is it from DM -1 ? or it's a test model ?

We might have this going in more than one thread....

Here's the new best thread, since it's a standalone article thread....

Now that DM1 capsule is lost - any ideas what capsule will be used for the IFA test?
a) DM2 capsule, to be reused for DM2 afterwards
b) DM2 capsule, another fresh capsule to be used for DM2 itself
c) fresh capsule for IFA (how much time will they need to pull the next one forward? Do we have public info for the readiness level of preparedness for the first rotation flight post-DM2?), DM2 capsule kept for DM2 itself
d) DragonFly/Pad Abort capsule (what's her status/location now?)
e) something else?

e 1) ... assuming DM1 shell is not irreparable, boilerplate something up quickly, using it after cleanout.

Considering what I've heard, they may be able to reuse DM-1's aerodynamic cap but nothing else.

What about C202, the structural test article?

Test like you fly. Use the DM2 spacecraft for abort test, then fly DM3 to orbit, and think hard before crewing same. There's going to be a schedule hit here regardless - and there should.

DM3?

My lay-thoughts - once the "anomaly" cause(s) is(are) mitigated - fly DM2 uncrewed, then repeat the same testing (that resulted in the "explosion"), then use DM2 for the IFA, pushing the IFA to after DM2.
If all goes well, then Crew-1 could be the first crewed flight (or possibly a DM3 if concerns remain).

SpaceX would only refly the uncrewed test flight if there is significant redesign of the capsule (e.g. abandoning the superdracos for a traditional solid launch abort tower). It is too early to tell if that will be needed.

Wouldn't they still have to use hypergolics for Draco thrusters even if they go to solids, just not as much? Super Dracos would use a lot more fuel. A solid tower over capsule would be a down and dirty, quick and easy fix for Super Dracos, but they will still need thrusters for flight control and docking. If this failure was caused by a nitrogen pressure tank, you still have to have pressure for thrusters.
