Dragon had problems with parachutes too. I wonder if the main difference between SpaceX and Boeing is turnaround time between design and test (and subsequent post-test review and updates to designs)?

Where to spend the money: the paper review, or fabricating a new test object to test an incremental change?

It's Boeing, they are going to hire 100 more MBAs to analyze the problem

Engineering companies should always have an engineer at the helm, having MBAs they’ll just try to cut costs

Guess what Boeing did? There are a lot of interesting reports on what has gone on at Boeing in the past 20-30 years. The biggest is that they cut costs on safety and reliability... hence this massive delay and cost overrun. They need to get back to the Engineering... and fast.

Yup ever since they merged with McDonnell Douglas, I’ve read that they been on the downhill in terms of engineering.

The financial aspects started mattering more than the engineering aspects.

737 MAX was just a complete fiasco. I was shocked to read anything in engineering, never mind aeronautical engineering - having a single point of failure with no redundancy.

Like you said, it happened in the name of cost cutting.

Anything human rated should have double redundancy. If a spacecraft, triple. My biggest concern with Starship. A human spacecraft should be over engineered.

I agree, I’m concerned that Starship has no escape module.

I imagine that Starship can escape from the booster section if something goes wrong, but there should also be an escape method if something was wrong with Starship itself.

I think the entire top 25% should be a large detachable capsule in any human variant. Cargo and tankers no.

But the shuttle didn't have an escape system either.

Boeing didn’t merge with but were devoured by MDD. Ever since the company has been trying to move away from commercial aviation and into the D.C. Area.

One thing about commercial sales; your goal is to keep your customers happy and well-supported. Something Boeing appears to have given up on. With government sales its all about keeping key Representatives and Senators happy by keeping constituents employed. Once a procurement pipeline opens the goal is then to keep it open.

Thomas P.M. Barnett gave a talk about this to TED back in 2007. He described how government agencies come to congress for appropriations. If NASA, say, said “SLS will be billions over budget and launch twice in 8 years” then congress wouldn’t fund it. But, if you say “Its a new rocket and spacecraft with amazing engines that will take us to Mars and beat the Chinese/Russians” then they ask “Will you build it in my district?”

Old cartoon in the New Yorker during the Reagan years: “It doesn’t have to fly. It just has to fund...”

I used to work for another large defense and aerospace company (ATK) and this was my biggest complaint. Management would laugh at me when it frankly said it a few times.

On the other hand, I was impressed at the performance of the only two Artemis missions: an orbital run in 2014 and multi week lunar run in 2022. However, a huge cost and delays.

Yeah for as much bad rap as SLS gets, it had an actual spectacular maiden flight which is pretty rare for rockets.

Parachutes are hard. Which is a bit funny since they are so flexible. They are hard because they are so flexible and can be greatly impacted by hard to analyze forces.
