I have seen the video & it's very tragic (For those who want to see it, PM me and I'll send you a link). It's quite comforting (I cannot find the correct word), to see the love which Eric Lamaze had for that horse - you can see the concern in him as Hickstead falls to the ground. I know I'll be waiting for later press-releases on the event.
I hope for one, that this tragic event reminds us to never take our horses for granted.
RIP Hickstead <3.
