  • Satellites do have such restrictions. While you may expect the angle to be higher than for an aircraft, a satellite will not be directly overhead most of the earth. You’re still limited by angle and shadow, as well as time and frequency. Unless the target is high enough priority to reposition the satellite, it will be an oblique angle at a predictable time. While that angle will on average be higher than an aircraft, the aircraft can find different angles, at different times, with as much frequency as you like.

    Perhaps some things are more visible to an aircraft from the east than a satellite from the north, or perhaps the target has camouflage procedures at the known satellite schedule but an aircraft is more likely to catch them operating

    Don’t you check upcoming meetings? Such as at the beginning of the day?

    Once accepted, why would you care when any specific meeting is, just which ones are coming soon?

    Granted I track things requiring significant effort through other mechanisms, so my meeting prep is more typically checking statuses and collecting data/summaries


  • I don’t know what to say: I can’t believe it either. Granted this is from a white male perspective and I realize I’ll never even notice most of it, but wtf?

    • Before the current MAGA, I hadn’t seen blatant racism in many years, not even private jokes, we seemed to be making progress on systemic racism, and in general had a more diverse, healthy society (obviously I’m not claiming racism didn’t exist, just that we seemed to be making solid progress, from my privileged viewpoint)
    • Now blatant racism is popular? We’re reverting any recent progress? We’re saying the quiet part out loud? Even the worst parts of humanity are encouraged to speak up _and find people not ashamed to support it? And people get elected despite that? And the only federal agency with a massively increased budget seems based mostly on racism?

    I used to believe conservatives were just people with different ideas how to make things work better for all of us, but wtf? How did this happen?
