I was at 34,000ft, it was -57C and I had never felt
such wide open space before. The actual drop was very extreme: in the thin air,
I dived 100m head down. The acceleration was huge. The rest of the flight was
very tranquil and fast: 120km/h groundspeed at 10,000m. In Cross Country 202
(August 2019) and as he approaches his 50th birthday, pilot and photographer
Matthias Küffer recalls the flights of his life,
including the day he launched his hang glider from a hot air balloon 10,000m
over the Swiss Alps.
