  • I have heard this tape. While it’s distressing, it’s something worth hearing. Not because it’s pleasant to listen to people die. But because it’s worth remembering their pain so that those mistakes are never repeated again.

    Remember that the engineers, technicians and other support staff of Apollo 1 didn’t have the option of turning off the audio either (I listened to it to partially feel what they felt). They worked feverishly to save their colleagues who were burning to death only a few inches away from them. And to finally reach them to find out that it was all in vain.

    This would have been a horrifyingly painful experience for NASA. And it did have an impact. NASA changed in an instant. No effort was spared in keeping the future astronauts safe. So much so that a deeply crippled Apollo 13 still made it back safely. And no lives were ever again lost on the Apollo missions. That’s the power of a personal connection to a tragedy. I watch a lot of accident investigation documentaries, including rail, aviation and space. Nothing drives the lessons deep like the depiction of human tragedy.

    Just imagine. If only the aircraft manufacturers could see the final moments of the passengers that die in their low quality aircrafts. Perhaps they would try hard to avoid such incidents rather than chase profits at any cost.

    RIP: Gus Grissom, Roger Chaffee, Ed White. The bravehearts of Apollo 1.











  • The latter - targeting from ground. While that sounds daunting, it’s already possible. Sats can aim data laser beams at other sats at even higher relative speeds.

    Beam decoherence is a pretty big problem when you are lasering through the entire atmosphere, and both scenarios require an astounding degree of precision.

    Beam coherence is the only problem with targeting sats from the ground. But remember, these sats come with big telescopes to collect as much light as they can. It may not take a lot of radiative flux to overload their sensors. I wonder how much it will take to completely fry them.



  • There are two disturbing tendencies being demonstrated here:

    1. Using useless AI to engage and disperse complaining customers. The AI can’t make meaningful solutions to many customer complaints. But companies use it to annoy the customers into giving up, so that they can save the cost of real customer support.
    2. Either blaming the AI or insisting that it’s right, when it makes a mistake. AI by nature is biased and unpredictable. But that doesn’t stop the companies from saying ‘the computer says so’.

    These companies need a few high profile hefty penalties as a motivation to avoid such dirty tricks.
