yeah, its one of the things with gliders.... try going up on an autorotating helicopter! lol
actually, I've done that before
you'll need a lot of wind but it can happen....
just a few weeks ago I tried to land on a 9000ft paek to pick up firefighters and the winds were so strong up the hill (on the side of a cliff) that the helo wouldn't land. I was light on fuel and empty....
Had to pick another spot. (you don't wanna be in an auto 30ft off the ground just sitting there because if the wind DOES die down.....

)
And the Muppet and I had a similar experience during training this spring. I lowered the collective to land but instead went up cause a sudden gust got a hold of us.
We must have shot up 500ft before we leveled out.....
