If you are overflying a dense forest and are forced to land - chances are you're going to be landing in the trees. And while landing in tree grove wouldn't be your first choice, there are a few things you can do to make it survivable:

• You'll want to use a normal landing configuration with full flaps, gear down (extended gear would definitely have a protective effect on the cabin area) and land into the wind, so your ground speed is low. When you "touch down" on the tree tops, you want to be at the slowest airspeed possible without stalling, so you can hang the airplane in the trees in a nose-high attitude. By keeping the nose high, the entire bottom of the plane can cushion your initial impact, as well as keeping branches from breaking through the windshield.
• When it comes to choosing the right trees to land on, you want to try to pick trees that are low and closely spaced, as opposed to tall trees with thin tops. It might be hard to convince yourself the dense trees are the better option, but they can cushion your descent all the way to the ground.
