On 14 July 1985 Boivin again broke the altitude record for a hang glider by launching from the summit of Gasherbrum II (he had reached the summit the week before, on 8 July, and reclimbed the mountain to make his jump). On 26 September 1988, having climbed the mountain via the south-east ridge, Boivin made the first paraglider descent of Mount Everest, in the process creating the record for the fastest descent of the mountain and the highest paraglider flight. Boivin said: I was tired when I reached the top because I had broken much of the trail, and to run at this altitude was quite hard. Boivin ran from below the summit on 40-degree slopes to launch his paraglider, reaching Camp II at in 12 minutes (some sources say 11 minutes).
