Safety glass -- how necessary?

[Phil Nelson]

I understand the reasoning behind putting a safety glass in old TVs.

I'm wondering whether anyone has seen or heard of a case in which a CRT imploded during normal operation.

Trying to think of a scenario in which this occurs. Maybe a Bad Thing happens while you're watching Bonanza, causing a chassis fire, and then the CRT pops . . . ? Or would the CRT just pooch out backward, leaving the front intact?

Was the glass there to protect against a significant danger? Or merely an extra precaution against the occasional ape who bashed the TV while trundling it around the house?
