While the previous flights and crashes seemed par for the course for the innovation SpaceX is pushing, but this one somehow feels like a wasted opportunity, more due to hubris, lack of attention and a simple rush to get things moving to keep the launch cadence going. Just a gut feel.
For example, its not sure why they would press forward launching on a zero visibility day? I understand you get telemetry and that is the most important data, but a visual also adds a lot of value in an aftermath like this, by helping you reinforce your conclusions you make out of telemetry data. SpaceX has some of the smartest engineers, but this launch looks like was done in haste.
