I witnessed one of the Ford fans disassemble themselves on a friend's 5.0 mustang.
It was about thirty years or so ago.
He had just installed new mufflers and (I think) a new, open-element air cleaner.
There were about six of us standing around the front of the Mustang chatting.
He had the hood open and he was revving it up so we could be impressed by the 'new' sound.
His final rev was probably to around 6k and the fan let go.
Fan blade glanced off the hood and landed about 50 yards away, behind us.
Water pump exploded with antifreeze all over the place. Lower hose was shredded.
Water pump pulley jammed down between the timing cover and the crank pulleys and stopped the engine instantly.
Alternator was spinning about 100k RPMS - sounded like a siren. Took about two minutes for it to slow down and finally stop.
I've had a healthy respect for all fans ever since. Especially at any kind of RPMs.
