Racing community hoping Schumacher improves
The motor racing world, and in particular Formula One, is known as a cut-throat business.
However tragedy is never far away in such a dangerous sport with legends such as Ayrton Senna and Dan Wheldon succumbing to racing accidents.
And when that happens the whole industry comes together - and Michael Schumacher's tragic skiing accident has once again galvanised the racing community.
Schumacher, seven-time World Champion, is still in a medically-induced coma, fighting for his life after hitting his head on a rock while skiing off-piste.
Former colleagues, bosses and those in other racing sports have been quick to take to Twitter to share their thoughts on the legend.
Here are just a few of those:
