Detailed timeline here:
The first link has the greatest detail, the second is more summarized and is what I called out the highlights from.
I've called out *highlights* so thie quoted timeline is not the full timeline (I removed some of the internal JSO times, for example) but these are is VERY lengthy and thorough.
Both cover the time only after JSO was called in.
