Is it possible to drop a payload via anchored parachute?
I'm trying to drop a payload via parachute with some accuracy.

Cut a hole in the middle of the parachute, make its edge smooth and install a pipe through the center of the box that contains the payload. Run the line through the pipe and parachute and let the payload fall from the balloon. I believe the trick will work for small parachutes able to deliver up to 10 kg to the ground.
