    Change your thought patterns. Minimise their actions in your mind.

    They are not “psychopaths”, they are just “idiots”.

    They do not “counterattack”, there is no “attack” from your side. They are just “being a nuisance”. Frame all the bumps and thumps as renovations if you want.

    When they make a noise, turn UP your tv, just a little, so you can hear it over it. “Gee those renovations of theirs are a bit noisy, maybe I should put in a complaint.”

    When they rattle the ceiling of their apartment, “Hey it must be time to vacuum, thanks for reminding me. I’ll do it now while you’re renovating and making noise so it doesn’t disturb you too much”.

    “I hear that plants respond to music so I’m just going to leave some on for Ferris, my pot plant, while I go out shopping for a few hours this morning” - Not too loud, just loud enough for Ferris to enjoy it. If you hear a lot of thumping it must be just them taking the opportunity to renovate while you can’t hear them. I do hope they don’t damage their ceiling with all that thumping while you’re out, oh well.

    All that activity on their part takes a lot of energy, your activities take very little. Which one do you think is going to end first?

    standard practice to find these potential leaks with intensive pre-flight checks to identify and solve these issues before they escalate into a catastrophe.

    Except these particular leaks are due to vibration modes (on the newly designed vacuum jacketed fuel lines) that seem to be only present at high g’s towards the end of the burn.

    After the first ship to use these new lines blew up, SpaceX made some changes and conducted a minute-long test firing on the ground of the second ship. A minute of the rocket going through various thrust levels on the ground is plenty of time to pick up issues if it was going to be visible on the ground.

    Presumably it looked ok, so they launched it, and the second one blew up. They probably added more sensors on those lines, because they seem to be pretty sure that vibration modes are the issue on those lines now.

    Yes, you could model this, and no doubt they did to some extent, but nothing beats testing in real life unfortunately.
