Abstract
A balloon is provided having a balloon envelope, a payload positioned beneath the balloon envelope, and a drag plate positioned beneath the balloon envelope and attached to the payload, and a control system configured to initiate a process to cause the balloon envelope to no longer provide lift to the payload, wherein the drag plate serves to slow the descent of the payload to the earth.
