The only flywheel explosions I know of happened at a race track.
The stock flywheel was designed for daily street use not race application.
The scattershield is a bell housing replacement made of steel.
There are shrapnel blankets, for lack of a better or correct term, that are
used on dragsters; A/T wrap and blower tie down come to mind.

Subject: Re: [Tigers] Flywheel explosoins (was Best Clutch Kit 289)
Hi. This is all very interesting, but how common a problem is this in
reality, statistically? I mean, how many cars are out there
(Tiger/TVR/Cobra/Mustang/Fairlane/Galaxie/Falcon, etc.) that are still
running their original flywheels? Are they all really in danger? If one
were planning to drag race a car like these, of course it would seem to make
sense to change out the flywheel, but for street cars, when was the last
time anyone heard of a flywheel disintegrating? I honestly can say that I
have never even heard of such an incident on a street. I think it would be
interesting to understand how grave an issue this really is before spending
money to buy a new flywheel.
Regarding the scattershield, is this a replacement for the bell housing, or
is it something like a bell housing helmet, covering it? How many of you
out there have scattershields on your cars? How many of you have ever seen
a scattershield? I never have, but my experience with American motors is
relatively short (outside of Jeeps). Thanks. Mauro

I haven't seen a flywheel explode, but I've seen a couple of blown clutch
pressure plates, a driveshaft pretzeled, and a brake disc failure. Seen
pictures of damage done by a fan that shed blades.
I don't recall what damage the pressure plate did to the car (besides
leading them to DNF again and leaving a bunch of totally heat-checked
shrapnel under the car), but the driveshaft failure was caused by the
transmission somehow engaging two gears when the car was at about 90 or 100
MPH on the front straight at Race City. The driveshaft buckled, kicked the
entire passenger floor up about four or five inches, and then locked up the
rear end, which sent the car into the grass just beyond the end of the pit
wall. Ten yards earlier and he would have hit the wall.
The brake disc was machined beyond any reasonable thickness limit, and when
it got hot and the brakes were applied, a piece let go and locked the disc
to the caliper. The strut was nearly ripped right off the car (240Z).
If rotating stuff is suddenly made to stop, or if it can shed pieces, it
will do a lot of damage...
