It actually occurs to someone to put on skis and a parachute and glide down a chairlift cable.
On Facebook, the daredevil, Valentin Delluc, describes his pursuits as "speedriding" and "speedflying." The ride featured in the video above makes a buzzsaw-like racket, but the footage is spectacular.
"What mastery!" one YouTube admirer wrote of the stunt.
Just in case anyone gets ideas, Delluc warns viewers not to attempt this.
