This is smaller plane, maximum takeoff load is about 20 tons, and it probably wasn’t fully loaded, full semi-truck can be about 35 tons so it isn’t that impossible, aluminium is super light material.

Honestly if you want best free cad program there is nothing close to FreeCAD, sure UI isn’t super modern but as someone who had to use CATIA in high school it looks amazing, just slap dark theme on it so it doesn’t hurt your eyes. If you are up for paid version there is BricsCAD but price is spicy, not sure if it is possible to find pirated version for linux or if you are even interested in fucking with that.

From personal experience only distros that ever broke on me after update are Manjaro and Debian sid. I’m not claiming it is not my own fault somehow or my specific hardware problem and it did happen long time ago but if I want rolling distro I would go with something that is specifically made for it. I had good experiences with openSUSE and Arch so I would recommend something of those two. Also staying on Debian stable is not that bad nowadays when you can get newest packages with flatpak.

What in the fuck is HoloISO?? 2 minutes of research would tell you to get Mint, POPos or something similar and he finds some insane distro no one heard about. Guess everyone can be a tech journalist today.
