How to make smoke to signal someone in a airplane or helicopter.

If you are stuck in the wild you need to plan for ways to get out. One of the most frustrating things is when someone is stuck in the jungle is when they see a airplane or a helicopter but they cant signal for help. You should have a fire reader or at least a way to make a fire incase you hear oncoming airplanes or helicopters. The best place is on a hill or a place with no trees. If its in the middle of nowhere and there are usually no people they will notice smoke, but you have to get their attention. Here's how. Wet wood. That's it. Throw wet wood on a fire and it will smoke. Leaves also works. If you cant find any leaves or wet wood, use live plants and if you cant find a plant throw in your some of your clothes. But the answer is wet wood works the best to make smoke.
