  • Back in the early 70s, NASA engineer tests on a part indicated that a joint with 2 O-rings was too wide and could expose the o-ring. Northrop Grumman and NASA’s project manager said it was fine, 2 o-rings meant one was redundent right? and the design made it into the solid rocket booster.

    Then in 1977, a different test indicated 1 oring was letting gas during certain levels of mechanical stress. The engineers proposed a solution, which was ignored.

    Then in 1980, they asked to test what would happen if 1 oring weren’t there and what would happen if the oring was cold. This was denied.

    Then in 1981, a return booster was inspected and they found soot between the orings and one eroded, and the problem was added to the critical issues list. And ignored.

    This happened again in 1984.

    In 1985, they realized when the oring was cold at launch, the problem got way worse. Northrop Grumman finally changed the design to fix it.

    But they had a bunch of the old, unsafe part laying around, and NASA didn’t want to miss deadlines, so in January of 1986, they launched a shuttle with the part that they knew was unsafe in cold conditions, coldest morning they’d ever launched and a middle-school class watched a live stream of their teacher exploding 10 miles in the air.









  • people don’t deal with Elon when buying a Tesla, but they do have to deal with shitty dealers when buying another brand.

    I’m not gonna defend the state of the dealership system, but from what I hear, getting Teslas fixed is awful in unique ways.

    Tesla is going to end up the largest car manufacturer in the world.

    They’re the largest by stock price, but in EVs/year they were surpassed by a chinese company a couple years ago, and both traditional and new companies are closing the gap Tesla got from all the early capital that was dumped into them. They never came close if you include non-electric cars.

    Other manufacturers cannot make profitable cars at the price point Tesla is offering.

    There’s tons of electric cars at the price point Tesla offers, with a fraction of the issues. One thing I did notice is other companies limit what they’re willing to import into the US to avoid competing with more expensive models (eg, no company imports cheap electric convertibles or station wagon because they’d compete with higher-end electric cars and SUVs/pickups respectively), but I’m not aware of any market segment that doesn’t have a competitive non-tesla equivalent.

    Awhile ago, someone counted the number of local news stories of people getting immolated by their Teslas. It was more per car sold than the Ford Pinto.

    Between:

    spoiler

    Locking the person in when power fails

    Wompy Wheels

    Steering wheel come off while you are driving

    Tesla’s tendency to drive into the back of stopped emergency vehicles or stop on highways due to changing light conditions

    The trunk

    $500 door handles with 10 dollars worth of electronics that fail due to moisture and ice (this one was improved. They’re still $500 though)

    The car lying about its range

    Shoddy build quality

    A dozen other issues I hear from Tesla owners

    The only way I can understand Tesla not being as big of a joke as the Ford Pinto is some combination of outlets that would amplify these stories to become national news also tend to own stock in the largest car company, and Tesla having a team that’s 10x better than Ford’s at shutting down negative publicity.
