There's already been a plane crash (FD1), a car pile-up (FD2), a roller coaster malfunction (FD3), a race car accident (TFD) and the recent bridge collapse (FD5).
The most likely next scenario is:
An elevator collapse.
I'm rooting for an elevator mishap, massacre or bank robbery.
I'm excited to see what premonition scenario the minds of Final Destination come up with next!
