You can bring 10 things with you getting dropped into the jungles of Borneo. What do you bring?
I know, I know, this is weak sauce. Personally I'd bring a major caliber revolver and 1 bullet and that's it. I hate the jungle.
You aren't there for any purpose other than you probably want to leave there someday soon. Keep in mind the political and legal framework of Boreo and your precautions thereby. Presume you are wearing a flightsuit and helmet, jungle boots, and that parachute. You have all your shots.
Satellite phone and bank account numbers you can transfer to other people is a way to go. A list of phone numbers of people to call. So, one phone, one list, and 8 bank accounts. You call people on your list and beg for help, using the bank accounts one at a time to pay/bribe them for assistance to get you the hell out of there?
No, that goes against the spirit of the thing. Assume you are walking out and not communicating with the outside world. And you gotta carry your stuff out of the airplane so you aren't bringing a dirtbike and a recoiless rifle. Personal items. 10 of them. Including any additional attire you may desire. Try to restrict your self to one firearm, if any. That and 4 reloads for same count as 1 item of the 10 you are restricted to. If you want more ammo, each reload counts as 1 item. Not that you'll be shooting your way out of Borneo solo. Think downed pilot surviving post ejection. In the hot and steamy jungle. And we aren't at war with Borneo.
