Seems that the drogue that was supposed to yank the 3rd chute out, separated for whatever reason. So, the 3rd chute was never pulled out. Scary thing about that is however that happened, it could happen to all three.
As for the SM crashing into the ocean, true, BUT, it's going to smash when it hits the water, and bust a lot of stuff, the plumbing if not the tanks directly. At least some of the Nitrogen Tetroxide will get out on impact, and more will bubble up from the sinking SM wreckage. If the wind direction is not favorable, then the wind could blow that toxic cloud to the rescue vehicles and the spacecraft. Imagine having to keep the astronauts inside the spacecraft for an hour or two for those fumes to dissipate.
ALSO, the spacecraft is getting bathed in Nitrogen Tetroxide after the flip-around maneuver. I was REALLY surprised by that stuff being "dumped" (????) out. It's as though the recovery crews may need to wear HazMat suits and "wash" the spacecraft to remove residue, before opening the crew hatch.
As for the video, no conspiracy BS. This was flown at White Sands, all the camera views in flight seemed to be White Sands cameras. The camera with the closest-up view, they switched to, as the operator had trouble keeping it in frame, and the autofocus (?) took it out of focus for awhile. I expect most of the other cameras had good views, but not as close-up. Certainly NASA and Boeing will have those camera views to use in reviewing what happened. Except since it's pretty certain that a drogue chute came unconnected for whatever reason, a wider-back camera view may not be as much use as studying the actual hardware itself, to see what broke or became disconnected.
If the drogue connection was burned or melted, they will be in DEEP CRAP (and I don't mean "crap"). All those hot gases coming out the back of the SM after the flip-around, it really does make me wonder if the thing got burned/melted. I am not even so sure those hot gases/venting after burnout was supposed to happen, it's bizarre.
