Which would suck more, being the first base jumper to realize you're not going to make the jump successfully or the second jumper behind the first?

Two base jumpers just tried a jump with the winged suits from 3500 feet in Yosemite Park, and both crashed into the rocks when they couldn’t maintain enough altitude to make the crevice they were trying to get through. It made me wonder which feels worse? Being the first and realizing you’re toast or being the second jumper and watching your friend crash and knowing what’s coming?
