Gov customers will sometimes expect or ask for margin above design FOS for testing beyond failure.
Designing to 0% margins is often more expensive in terms of engineering design, rigor and schedule.
Contracting is bring me a rock mentality with gov. It doesn’t always make sense.
Sierra Space's LIFE inflatable space station module undergroing a full-scale pressure test:

It burst at 427% of its operating pressure, well above NASA's requirements.
What is happening to #silver ??
Never thought I’d see Eagles over 50$
Boeing ‘Bird of Prey’ might be one of my favorite X-Planes.
It’s believed it was designed to prevent shadows and possibly active camouflage.
The Iron Claw is one of the most gut-wrenching movies I’ve watched since having a son.
The fact they left out another brothers death because it would have been unbelievable is insane.
The James Webb telescope is so powerful it can effectively see into the universe’s past.
Humans have been pushing the boundary of playing god for so long I don’t understand how making it rain more is such an overstep.
Key to diffuser design: understand Bernoulli’s Principle & Continuity Eq.
Bernoulli’s: relates pressure & velocity in fluid (air) streamline.
Continuity Eq.: links area & velocity.
Constricting fluid area boosts velocity, lowers pressure (e.g., thumb over garden hose).
In college, I hand-built a race car underbody diffuser.
Diffusers on F1 and road cars share the same basic function.
By constricting air beneath the car and rapidly expanding it at the rear (diffuser element), it effectively sucks the car to the ground, like a vacuum cleaner underneath.
A rare 35-star U.S. flag 🇺🇸 is for sale.
The 35-star flag was created after West Virginia's secession from the Confederate state of Virginia during the Civil War.
The 35-star count falls within the active Civil War years and is extremely rare.
For the love of god have kids.
There’s a man in sub Saharan Africa rn with 6 kids burning dung for heat with no running water who can figure out how to provide for his family.
Stop worrying about your net-worth and just do it.
Took creatine for the first time with a double shot espresso on an empty stomach.
Is this what meth feels like?
They need to make more road trip horror/thriller movies like they did in the 90s/00s.
Joy Ride and breakdown are some of my favorites from that era.
Found this USAF patch for sale for the Ryan Q-2C Firebee from the 1960s.
With drone warfare and manufacturing needs in focus, it’s notable that the US has built drones for nearly 75 years.
The Firebee, first flown in 1951, was an early jet-powered UAV used for targeting.
