Contributing factors in both incidences: these pilots were flying in inappropriate locations to prevailing conditions. We are continuing to see this with many pilots at our more complex non simple ridge sites like Little Black and Palomar to name a few.
It is never a bad time to step back to a slightly more conservative flying style, a safer wing, or more mellow hours of the day. Review your training books; read "Understanding the Sky" and "Speed to Fly".

Again. Remember that paragliding and hang gliding are really dangerous, and your family and friends want you to be safe more than they want you to fly high and go far. Remember no one cares how long you stayed up, if you set XC records, or do cool acro. No one. Really. You are the pilot in command of your glider, or your wheelchair, and of your life.
