@JackRacc My concern is largely that of the "go fast and break things" approach may have worked within proven design envelopes like dragon was operating in but doesn't at the edge of material science we are operating at.

The sheer waste of relearning lessons the hard way rather than taking a more methodical design process with in-lab testing of the upper stage under similar physical loading conditions is managerial and engineering malpractice.

This is best demonstrated by early failures because SpaceX didn't want to use a vibration arresting water system like similar vehicles have used for years to disastrous effect. This is not a lesson they needed to learn the hard way and the homework was already done.

This shows a complete disdain for work and education of the experts in this field that typifies the ideology of Musk in a nutshell both politically and in terms of design rigor. His mental far right crash out is effecting his leadership.
