  1. We still use the Inertial Guidance System on large planes today where we would align the system at the airport gate prior to pushback and takeoff. I assume in Apollo it was aligned prior to launch?

  2. @12:35 If Drapers experiments had only used a "simple electromechanical device" to read the data from the gyros and turn it into flight instructions then it would have no way of being able to automatically correct for the change in angle and acceleration due to the earth's curve rotation…. so how did it manage to navigate the plane… that is the real question.

  3. And, yet today, 50+ yrs later, Boeing can't even get the hardware, software, and instrumentation correct for implementing the MCAS system on their 737 Max 8, earth bound subsonic jet powered airplane!!!

  4. 17:40 Priorities: In the late 1980s I worked in computing for a major bank, running IBM systems. The most common system message started with the code $HASP, followed by a numeric, eg $HASP412. These told us what was happening to each task within the system. HASP stands for Houston Automatic Spooling Priority.

    Our 1980s banking systems were children of the Space Race.

  5. I became a professional programmer in the mid 1970s, specialising in real-time and embedded systems. I worked with many computers that had a lot less memory than 78k. Once you ditch the Micro$oft bloat, ditch the language APIs, ditch the fancy GUI and graphics, ditch the audio, ditch the web connectivity, write in assembler, and ditch all the other unnecessary bells and whistles, you can do an awful, awful lot in a "mere" 4k. Having a massive 78k sounds like luxury indeed.

  6. If I ever have children I will show them this. I will try to explore their interests and see if I could show them beauty in reality. When I was younger I used to want to go to space. Now that the second space age seems to be approaching I want to go to space someday.

  7. all the systems of guidance and telemetry must have been very important , wonder why nasa said they lost it all , misplaced or destroyed it , and was reason they gave of why they havent been back . or …

  8. Apollo lunar landing, July 1969… it was an incredible moment to be around, at the end of a crazy decade. Most of us in the civilised world must've huddled close to grainy black-&-white TV sets to witness this amazing spectacle. As with other landmark events in modern history, such as the 1963 assassination of President Kennedy, we can all remember where we were at the time.

  9. I think now it is fairly evident that mass trolling was stepped up substantially about 3 years ago. The time of all these went to the moon comments. Or utub allows pre dating of troll comments. Not worth discussing that all these alleged people would have to be incredibly stupid. But more incredibly stupid are the backers of the trolll program. People will be seeing through this horse pucky in ever increasing numbers. This trolling helps that process.

  10. wasn't a checklist error, it was a design flaw. the two 800 hz power supplies that fed the ATCA and the CDU were not phased locked causing the ATCA not to respond to polls from the CDU which the CDU then reported to PNGS via an external interrupt. this error happened 12,000 time a second and occasionally there wasn't enough Vector Accumulators and/or Core Set to handle the interrupt causing 1201, no VAC, 1202, no CORESETS alarms. Since the priority tasks still had their VACs and CORESETs, the executive could flush out and restart the priority tasks: a warm reboot….

  11. Alright, howcome at 24.45 and 24.53 we have assTroNots turning there helmets in the vacuum of space? Those helmets could not rotate and keep a pressure seal! TWO; the "five balls" were never mentioned, an integral part of the "naviagtion compooper." Look, the MIT guys were dooped along with the rest of us. Oh and the failure? Scripted drama to keep people on the edge of there seats and keep watching the bullshit. May Grissom, White and Chaffe rest in peace. In my opinion the only ones that did indeed deserve a parade.
