Leaning in certain helicopters
After flying around for a while with my spanking new trackIR 5, and though it greatly increases my ability to land in difficult areas without the use of auto-hovering.
But i still cant see what is underneath my helicopter when i try to land, like small trees/bushes etc because obviously the bottom of the helicopter blocks my view.
However, i think one would be able to lean out of the helicopter a bit (perhaps a bit out of window, or out of the open side of a Little Bird) and check whats under you.
I dont know how realistic that would be, but it might help with not landing on a treetop
