 This technique has been used where the payload line is thin in comparison with the balloons size (large balloons can create a *lot* of tension on the line in windy conditions).  The technique was developed by RocketBoy for [[http://projectspaceplanes.com/|Samsung Project Space Planes]] which need to use less than 230 N breaking strain line in order to be classified as a ICAO light balloon. This technique has been used where the payload line is thin in comparison with the balloons size (large balloons can create a *lot* of tension on the line in windy conditions).  The technique was developed by RocketBoy for [[http://projectspaceplanes.com/|Samsung Project Space Planes]] which need to use less than 230 N breaking strain line in order to be classified as a ICAO light balloon.
  
-The technique uses two lines - the first is the thiner payload to balloon line, the second uses a loop of thicker line - this is used to slowly let the balloon up until it picks the payload up - at which point one end of the loop is released.  A short line and slip block have proved essential to the correct working of this technique - otherwise the two lines can twist together and one cut through the other at release.+The technique uses two lines - the first is the thiner payload to balloon line, the second uses a loop of thicker line - this is used to slowly let the balloon up (1) until it picks the payload up (2) - at which point one end of the loop is released (3) the balloon and payload then ascend as normal (4).  A short line and slip block have proved essential to the correct working of this technique - otherwise the two lines can twist together and one cut through the other at release.
