ILLEGAL ON EVEREST By Hans-Peter Duttle “Unthinkable! Impossible!” - That's what Swiss Hans-Peter Duttle would have had to listen to before he set off for the Himalayas - if he had told about his plans back in 1962. But he didn't. He set off secretly to climb Everest via forbidden Tibet with three American alpinists. Illegally, poorly equipped, without altitude support, satellite radio or a doctor. The four of them didn't even have any altitude-appropriate sunscreen with them. It was - as Hans-Peter Duttle says today - a suicide mission. Trying to tackle an eight-thousander in this way was an absolute novelty at the time. Today it's called alpine style. Alexandra Rozkosny, Editor-in-Chief of “The Alps” – Swiss Alpine Club
