  • Shortly after pandemic I was on a couple of flights where they would make people leave in 5 row groups starting from the front. I saw one or two flights where people actually understood the instructions and everyone just stayed seated waiting for their turn. Then 5 rows would get up and leave. Then the next 5. It went very smoothly. I didn’t time it but it looked faster than the usual way.




  • Depends what SciFi we’re talking about. “2001: A Space Odyssey” plays like a total fairly tale now but I would say it was technically achievable to have lunar base in 2001 (but not going to Jupiter if I remember the plot correctly). Mars trilogy by Robinson starts in 2035 if I remember correctly and initial mission was based on cheap launch system to orbit. I think this was also feasible with sustained investment. A lot of other SciFi is based on FTL travel, AI or hibernation which we cannot place on some tech roadmap so we cannot say what does and doesn’t “lead” to it.


  • Plenty of things could have been done with proper investment even before going to Mars. Reusable rockets, cheaper launch systems, more flights to the moon, moon bases, space stations. Yes, Mars is difficult but it would be easier with well established presence in the orbit and on the moon. All of this happened way too late (or never) because no one wanted to invest in it.
