Shipping CRT's

Just a WAG here John, but if the tube had something loose inside of it large enough to cause that kind of damage to the phosphor, I'm guessing that either a) it had issues long before it was shipped, or b) it was knocked around enough in shipping to loosen the culprit up and cause the damage.
I've always just double or triple boxed them in cardboard boxes and held my breath. Packing peanuts and bubble wrap are your friends. There isn't much you can do to minimize shock. I've seen the equipment that most of the major shipping companies and postal services worldwide use; if a box can't survive a 6 to 12 foot drop onto a hard wooden surface, you probably shouldn't be shipping it period.
