Weather was great and we (with Olivier and Jonathan) went on top of the Jungfraujoch for a paragliding flight to Grindelwald. It ended for me with a missed take off, crashing in the steep glacier firn. Facing imminent danger to slip down the cliff, I called help and was saved by the Air Glacier rescue. Find the full analysis of what happened that day in the article "My Air Lesson", published in the SWISSGLIDER 09/10 | 2025 (german/french).
