An Unprecedented Hang Gliding Journey

  • 🚀 The pilot embarked on their longest hang gliding flight ever, covering over 80 miles to New Cuyama.
  • ⏳ The initial 45 minutes involved waiting for the convergence and seeking lift near the launch site.
  • 🛠️ Preparation included donning a pod harness and helmet, launching with assistance into the air.

Experiencing the Convergence Phenomenon

  • 🌬️ The "convergence" was described as a meeting point of two airflows (west and east), creating a powerful lift band.
  • ⬆️ Once in the convergence, the pilot experienced smooth air and significant upward lift, contrasting with earlier struggles.
  • 🐦 Large groupings of crows below served as a reliable indicator of being within the convergence band.

Reaching Record Altitudes and Navigating Challenges

  • 📈 The flight achieved a personal record, reaching 11,000 feet for the first time ever on a hang glider.
  • 🥶 High altitudes brought extreme cold despite initial ground heat, requiring proper layering.
  • ⚠️ The pilot encountered "cloud suck," prompting a test dive to escape the intense lift and maintain control.
  • ✈️ A sailplane sighting at altitude was a memorable and "mind-blowing" experience, likened to a "dragon."

The Long Descent and Successful Landing

  • 🗺️ After losing the convergence, the pilot navigated east, spotting the New Cuyama school and airport 60 miles downrange.
  • 📞 Communication with ground support (Jay and LJ) was crucial for tracking positions along the valley road.
  • 🌪️ Near the landing zone, the pilot observed dust devils, indicating turbulent air conditions.
  • ✅ Despite the challenging conditions and unfamiliar landing zone, the pilot executed a smooth and successful landing after a three-hour flight.
