    Standard for identifying features on Engineering Drawings?

    JTaylor - interesting question - I don't have an answer. But the methodology you previously used makes sense. I am going to ping the machine shops I work with to see if feature identification would be beneficial to the interpretation of the technical drawings I supply to them. Regardless, of...

    SpaceX Starship missions

    RoarkS, what does BONG stand for? Blue Origin? How does developing a rocket "help ensure the future of the only consciousness, the only life we know of in the entire universe"?

    SpaceX Starship missions

    Agreed - the editorial comments detract from the tech descriptions/explanations.

    What is this Material & Specification? Please help

    I don't work with structural steel so this a wild guess: 11/16 inch Diameter Cold Drawn Steel Bar

    Help Identifying Callouts in an Old Drawing

    The items you have circled don't appear to be be geometric tolerances to me. They seem to be defining reference Datums or inspection points or flag notes. Do you have additional sheets of the drawing with general notes, etc.? Amazing tech described by your drawing! The thin-walled (~.09~.12...

    Toronto place crash

    ~25 ft deflection - quite impressive. The testing fixture is quite amazing itself. I image the wing has a gazillion strain gauges attached and the harnesses for these alone would be a major engineering task.

    Bird Stike on Take-Off

    Isn't the mechanism of damage different for the turbo fan engine compared to a straight propeller because the basic difference of the engines? The turbo jet section has internal clearances appropriate only for compressible fluid (air); ingestion of solid material will destroy the blades and...

    Omniscient Elon Musk seez....

    Dustin gave some great points and his presentation is quite engaging.

    Omniscient Elon Musk seez....

    If Musk really was serious about retiring to Mars then he has a highly romanticized view of life on Mars so do all the fanboys who think the BFG/Starship is a quick stepping stone to interplanetary flight for humans - all that remains is making orbital refueling stations, astro-tugs, orbital...

    Toronto place crash

    The simpleflying and AV Herald stories are from 2022 -2019. Is there significance to the recent Toronto landing? Endeavor Air and Bombardier airplanes, yes. Significance based on industry-wide statistics . . .??

    Omniscient Elon Musk seez....

    Humans going to Mars makes little sense to me, other than to say it has been achieved. Similar to climbing Mt. Everest - once you are there, little can be done, and no benefit outweighs the cost of sustaining the human presence. Mars is generally very cold (albeit, equatorial regions can reach a...

    CNN bio for David Soucie: ------------------- David Soucie is an aviation safety analyst for CNN. He has traveled the world in the interest of improving safety awareness. He’s worked in the cockpit, on the hanger floor, within the aviation boardroom, and inside the Washington D.C. beltway. He’s...

    Toronto place crash

    Not to nitpick, Dirtejoe, but the av-expert did state 'break away bolts', not explosive bolts. The mechanism of operation is significantly different for each type. Sorry, DirteJoe, I missed the explosive detail in his statement. Regardless, the wings shearing off definitely spared the...

    Calculate required amount of paint for mechanical spring

    Without a sketch or diagram of your exact process or knowledge of your cost/resource constraints: Do you have to limit yourself to an estimate/prediction of the amount of paint required? Or can you place various springs in the setup and run physical tests to develop your algorithm? Take your...

    BOOM lives up to its name

    Boom seems to be following measured development plan and the XB1 demonstrator has performed as designed and expected. Scaling up to passenger service capacity will be the next challenge.

    California Dreaming No More

    Avian flu is the reason for culling the chickens. What relevance does that have to wildfires? Discussion on climate change and human interaction is difficult enough, does a red herring need to be thrown in? Certainly, the wild fires have been devastating but as JoshPlum points out the Santa Ana...

    A completely new piston engine architecture

    Interesting rotary cam for valve ops.

    Boeing again pt2.

    Yes, as 3DDave has pointed out there was no saying DEI did not exist. It just is not the cause of the corporate and engineering failures. DEI is just a different wording for affirmative action and it all can be nice statements made publicly but not acted on in any substance. Regardless...

    Things are Starting to Heat Up - Part XIV

    The proliferation new descriptions has not helped: 'bomb cyclone' for a storm that has a rapid drop in barometric pressure has a better sound for news stories and every news outlet is hungering to get eyes so the copy is pumped with superlatives and 'unprecedented this' or 'unprecedented that' ...

    Things are Starting to Heat Up - Part XIV

    In ref to BridgeSmth's post: How is the science of climatology able to say storms are intensifying more rapidly compared to historical storms? Modern storm tracking with satellites allows observation in ways previously unavailable. How is speed of build for older storm known? Just a single case...
