Since in the movies, FD6 and FD7 will be back to back, I'm planning to make one. The story begins when Death realized that someone has messing around His Death's list, leaving 7 people survived from those five crashes and never died in freak accidents among the others. But, his ultimate design will be very fatal

Could you lend me a hand for determined the opening crash and also the freak accidents of the survivors (13, at least)?

Thank you
