Travellers of antiquity who could not solve the riddle of the Sphinx were strangled by the monster. Visitors of the eponymous rock formation on the Jungfraujoch need not worry about this. And they can travel in greater comfort: An ultrafast lift takes you to the observatory, an international research station. It climbs 108 metres in 25 seconds. They need do nothing more than enjoy the view up there. They can safely leave the riddles to the explorers.
