Following that crash involving the French, the Trinidad and Tobago team, the final team to compete in heat two having finished 27th in heat one, have also crashed.
All four athletes, including British-born Axel Brown, are walking to the athlete area.
France's Emily Harrop and Thibault Anselmet are the reigning world champions. Harrop, French born and raised but with British parents, finished second in the individual women's event while Anselmet won bronze in the men's.
Men's champion Oriol Cardona and women's bronze medallist Ana Alonso were second at the 2025 World Championships.
Switzerland's Marianne Fatton, the women's gold medallist, won bronze at last March's World Championships alongside Robin Bussard. She's partnering Jon Kistler (sixth in the men's event earlier this week) at the Olympics.
Alba de Silvestro and Michele Boscacci are carrying Italy's medal hopes.
After that promising opening run, Brad Hall and his sled could only clock the 12th fastest time in run two and it leaves their medal hopes hanging by a thread.
They will need a big performance in Sunday's run three and four to challenge for a medal.
Ski mountaineering (or skimo, to its friends) made its debut at this Olympics.
Spain's Oriol Cardona was the inaugural men's champion, with Switzerland's Marianne Fatton winning gold in the women's event.
And now it's time for the mixed relay, featuring 12 teams of two athletes (one women and one man).
Each athlete completes the course loop twice - alternating woman, man, woman, man - and each loop contains an ascent, descent, and two transitions (where skins, which help athletes grip the snow and go uphill, are removed/reapplied).
At various points, you ascend on skins or on foot (with your skis in a backpack). Descents are completed on skis (with skins in the backpack).
The final of the men's ski cross is just minutes away, and there are two Italians for the home crowd to cheer on.
Simone Deromedis and Federico Tomasoni are the home hopes - at least one of them will win a medal - while 40-year-old Swiss Alex Fiva and Japan's Satoshi Furuno will be trying to beat them.
The small final - to decide who finished between fifth and seventh - was won by France's Terence Tchiknavorian.
Norway's Johannes Hoesflot Klaebo is now the reigning Olympic and world champion across six individual and team disciplines. Sprint, distance, relay - no problem!

Klaebo waited, waited and waited and he is striking gold again at the right time.
Many, many decades from now when we've all gone, and Klaebo is an old man, little boys and girls will turn the pages of a history book and read about the time a Norwegian viking came to Italy and went home with a sporting war chest of gold because for one winter in 2026 he was unbeatable.
He is a legend of sport with 11 golds and his six here will never be forgotten.
