I work with CRTs all day on some days (unfortunately)
and once in a while
a monitor or TV will fall off the pallet I'm stacking, from heights of
anywhere from a couple feet to 6-7 feet. In most cases, the case gets
cracked up pretty bad but the CRT remains intact. If anything does break,
it's usually the neck or stem, and you can hear the hiss of the air
rushing into the back of the tube: nothing to worry about there. On rare
occasions, the TV or monitor falls flat on its face, and that usually
Basically, I'm generally in awe of the durability
of CRTs. I've dropped
bare CRTs before and they tend to just bounce. I've dropped monitors that
then continue to work just fine.

My coworker was taking something from shelf and unfortunely he
snagged a line cord belonging to the 13" tv sitting on top shelf 9
feet up and yanked it down I was only 10 feet away. That tv hit the
cement floor dead center on it's face with a glassine shrill "BOOM!"
Opened it up, yoke & neck went through inside the CRT leaving huge
jagged hole where flare used to be and only mark on face is scratch
marks.
I will not forget that sound. "BOOM!" of air imploding in a instant.
When I am disposing junk CRTs,
Yes, I have heard the "whish!" if neck accidently shattered or the
long fading sigh of "whoooosh" or a quick whoosh if the little pip
broken or a long, long hiss if someone cracked the pip partially.
I heard of CRT "explode" but my days was before the time when CRT was
just that, big glass bottles without implosion protection.
Over the years, I have heard of stories of TVs falling. Some made it
through, most didn't make it either CRT shadow mask wrecked or
circuit board in pieces or CRT cracked. Only one that stuck was a
older philips TV had chassis completely popped out of it's rails and
board is completely intact but CRT mask wasn't. Rails is very
strong and deep yet board escaped. Wow.
Plastic didn't make it very often. BTW, don't drop a Sanyo TV. :)
Their plastic is complete cr*p, simply shattered into pieces
like a lead glass. I even smashed through Sanyo TV cabinet plastic
when hitting it trying to get it to act up with a flat slap. :(
