I enjoy this mod quite a bit, but I wanted to keep playing past the first week as if it were a regular Zomboid game, after the outbreak.

There's no option to turn off the guaranteed airliner crash right now, so you can do the following:

Navigate to your Steam workshop folder. This is usually at

C:\SteamLibrary\steamapps\workshop\content\

You'll want to look for folder 108600 (zomboid)

From there, you'll need to navigate to folder 340318054 (The Mod ID)

You'll then go down to mods, BanditsWeekOne, 42, media, lua, client

From there, you can open BWOScheduler.lua using Notepad (or your preferred plain text editor)

Ctrl-F and search for "plane", the event name is something like "PlaneCrashEvent" (I also disabled all the jetfighter/bombing runs just in case)

You can remove the entire line for the plane event, it looks something like this (not the exact text):

tab[000][0] = {"PlaneCrash", {}}

Save the file. Now after the first week you can run around and try to survive all the bandits/zombies/etc as if you were in a (mostly) regular zomboid start. There will still be all the other events in the mod, except now you're not going to get Final Destination'd by a plane every time.
