Starting a dedicated thread here. After a pretty smooth flight test today, assuming no big anomalies occurred with the ground systems, it looks like SpaceX is back on track with testing and development. We should see more flights in the near future.
Both vehicles were lost before completing their full mission but a huge step forward today to see both executing the primary flight goals.

Never forget that taxes are the price of our civilization. Look around you and try to visualize what taxes have paid for... and the SUBTRACT what you see from the picture... it would be incredibly desolate 1800's image...

Tariffs on-the-other-hand are excise taxes on the purchaser. Pure BS.

Tug... What vehicle do you drive... 100% made in USA??? I have-to-doubt that... I have driven Chrysler and Ford products since returning from overseas in 1998... they have materials/parts from all over.

My daily is a made in Japan Lexus.

I understand what taxes have provided. They don't provide that anymore. Now, they feed money in to the pockets of law firms to comply with regulations the very same government imposed upon itself.

I hope this makes sense. I have been accused of TMI... TLDNR...

Musk/SpaceX want to play by their own rules and the Law of Unintended Consequences = ShitHappens.

Starters...

A few of my favorite sayings are...

"Play by the rules, but be ferocious." --Phil Knight, Nike founder

"Aviation in itself is not inherently dangerous. But to an even greater degree than the sea, it is terribly unforgiving of any carelessness, incapacity or neglect.” --Captain A. G. Lamplugh

"Always remember that you are absolutely unique. Just like everyone else." --Margaret Mead

"Engineering is easy. People are nearly impossible.” --variation

Meat and bones...

Regulations are in their simplest descriptions are 'common rules for everyone to abide-by' in an ever increasingly complex world... especially after the lawless world of pre WWII... in which 'anything went'... and the horrific spoilage was becoming evident. WWII spread our vison over the planet we live ON... and how technology was driving us forward without guides and guard-rails. Every country played by their own rules... and/or the laws and morals of their various religions... were absolute.

I am in aerospace... the rules/regulations we 'play by' were written in blood over ~120-years.... to avoid stupid/unnecessary bloodshed. As a 'mature aero engineer' I now know how mind bogglingly complex the average MIL and commercial aircraft is... and have seen elements/facets of aircraft/weapons/the-aerospace-system that 98% of my collogues are blissfully unaware of... because they are complex... and the don't wish to know more. AND I have been immersed in 13-crash sites...land and sea... picking thru pieces of aircraft wreckage co-mingled with shreds of aviator's clothing, boots survival gears... with blood and shreds of body parts... or not... and simply knowing a fellow human being was butchered... and sometimes burned... in that wreckage. The awful sites and smells of destruction comingled with death are... and never-should-be... unforgettable lessons learned. Especially from 'stupid/preventable stuff'.

Thankfully FAA/MIL reg's and documents of the USA are tough-fair-translatable-useful to the rest of the world... gold standard for safety and durability and knowledge and processes until there are lapses. And I have personally benefited from the mountains of lessons-learned and raw-knowledge produced-by the FAA/MIL and 'society' engineering/technical experts world-wide... including my personal engineering heroes. AMEN... I BELIEVE.

Can anyone seriously visualize flying today with the first rules and regulations for aviation published in the Air Commerce Act of 1926...? OR could anyone... who was flying aircraft in 1926... envision the aviation/aerospace world of 2025?

Tug... I am also, oddly familiar with a few USN and USCG guides and regulations for complex boats and ships... which share uniquely common elements with aviation. I know that You must 'play by regulations/rules/protocols/engineering principles' everyday... and they are are more familiar to you than Your family... and You know why they are so important.

OR, are You a rogue?

It's not the engineering regulations that are the problem. It's the bureaucratic rules that are some combination of nonsensical, redundant, or impossible to comply with.

Here is an example of one I'm working with right now, #2 and 3, how do you comply with something so vague yet so specific?

"Shore power is a CAECS. If distributed generation is used to supply shore power, the electricity generated must meet the following emissions standards:

(1) NOx emissions no greater than 0.03 g/kW-hr;
(2) PM emissions equivalent to the combustion of natural gas with a fuel sulfur content of no more than 1 grain per 100 standard cubic foot;
(3) Distributed generation GHG emissions must be grid-neutral; and
(4) Ammonia emissions no greater than five ppmdv, if selective catalytic reduction (SCR) is used."

For icing on the cake, the wrong subsection is referenced in the regulation so you can't even look this up.

No... we've been subtly 'Tugged' off the track.

Sigh... Tug... As I interpret...

Any shore-side diesel or turbine aux power unit [APU] must run on high purity turbine, diesel, SAF or CNG fuel to avoid localized air and water pollution... and NOT use low purity ship diesel, turbine or bunker fuel.

No diesel here, only R99.

I want to buy a US EPA Tier 4 final diesel engine but it's unclear if that meets "PM emissions equivalent to the combustion of natural gas with a fuel sulfur content of no more than 1 grain per 100 standard cubic foot". No engine manufacturer on the planet reports their PM in such units. Are you aware of any unit conversions?

Maybe a rocket scientist can help me achieve compliance. I'm trying really hard but can't do it on my own 😅.

Also, where can I find data to determine if my generation source is ghg neutral relative to the grid. Does this need to be done in real time, average per year? I shared the complete reg. That's it.

These regs took effect in 2023 and nobody knows how to comply. Not every industry gets the same quality of regulation as the aviation industry.

Anyways, this came up because governments have been using regulation for political purposes lately. Weaponizing of the Coastal Commission against SpaceX at Vandenberg had nothing to do with the Starship failures.

Tug... DANG.

Re theBard3's comment in post #126... "Are we still discussing Starship missions here?"

This Forum thread is for SpaceX Starship missions... enough said.

Re-post Your issue to either the Automotive/engines, Mechanical, Marine or Petroleum Forums... or, sigh... I'll red-flag-you off the Aeronautics & Space Engineers forums... for continuous, and distracting, off-topic replies.
