    1. Wait for the final report on Air India before taking any regulatory decisions.
    2. There’s no real technical limitation today on doing this to the safety-critical engineering standards that are demanded on the flight deck. The first CVRs were based on the old half inch tape technology, and they only recorded something like 20 minutes on a circular tape.
    3. Wait for the final report first; but exactly what additional information do you hope to get off the video feed that won’t be on the CVR + FDR? I am skeptical that this accident will not be “solvable” from the information that is available.
    4. If the regulators want to fight the pilot unions on this, they can. And they can probably win. Pilots don’t necessarily have a ton of leverage on this kind of issue.



  • As a country, we made a law that the ER has to treat you no matter what regardless of your financial status. That is an ultimate backstop: if people are about to die, as a society we decided that they should not if there is a means to prevent it.

    Medicaid is there to allow some people to go to regular doctors to save a couple of bucks vs. the ER. And it also pays for a lot of nursing homes.

    I guess what I’m saying here, is the headline is kinda misleading. ICE wants the data, true, so they can find deportation targets. But it’s probably more about inflicting additional cruelty, forcing people to ERs instead of clinics; or cutting funding to health care providers and forcing rural hospitals to close.









  • When this country was founded, tariff revenue was enough to fund the entire federal government. Those days are long gone, and they’re not coming back.

    Nowadays, there are basically two reasons to play the tariff game. 1. Extract tariff concessions from your trading partners, and 2. Encourage domestic production. The problem is, if you’re going for #1, you have to be willing to drop your tariffs at the drop off a hat to make a deal. If you’re playing #2, the people that build factories and whatnot want assurances that the tariff supports will be in place for years and years.

    So you can see that there’s an inherent trade-off between #1 and #2. To some extent, you cannot serve both masters. But Trump has been playing both strategies at the same time without a care in the world. There are… consequences… to doing that, which I am sure we will all get to experience.

    Edit: okay, okay. This Bolsonaro thing is a brand new strategy #3 which I’m calling… Oh geez… I gotta go buy some more beer.





  • A while back, people in Florida built an absolutely massive airport in the middle of the Everglades. They wanted to build the next big regional hub covering all of South Florida, but that never happened. So there’s a massive gigantic 12,000 ft runway, huge amounts of concrete apron, and space for a big passenger terminal that was never built. The runway remains open as a general aviation airport, and was until now mostly visited by students to practice touch and go landings.

    My points:

    1. The article summary saying it’s an airport used for training is true, but slightly misleading.
    2. There’s a lot of things about this place that make logistical sense for the type of operation they want to do: cheap rent or land, lots of available concrete, not actually new build (easier environmental impact statement), easy on site access to a massive airport that can support jets of any size, low amounts of air traffic, and secluded from public view.
    3. It’s not actually in Everglades National Park, and they aren’t filling in wetlands, like I’ve seen some say.

  • Non-Euclidean geometry was developed by pure mathematicians who were trying to prove the parallel line postulate as a theorem. They realized that all of the classic geometry theorems are all different if you start changing that postulate.

    This led to Riemannian geometry in 1854, which back then was a pure math exercise.

    Some 60 years later, in 1915, Albert Einstein published the theory of general relativity, of which the core mathematics is all Riemannian geometry.
