@WowSuchCyber @SecurityWriter At the cost of 2.5% of US GDP over a decade. And that was a multi-stage vehicle with no need for the structural integrity to land anything except the final return stage.
I should perhaps amend my comment to expand the thought. "If you have 2.5% of the GDP of one of the richest nations on the planet for 10 years and your problem constraints involve being able to discard about 95% of the vehicle in mission success, you stand decent odds of mission success with no catastrophic vehicle failures. If you're also lucky (If that pogoing problem had gotten much worse it would have ruined the vessel, and it would not even acceptable for crew).
