What about watching this type of video - is it useful for our awareness as
pilots? I tend to think it is, but that's just a personal opinion. Where I grew
up, the State Police used to do an auto safety presentation every year to
students who were about to get their driving licenses. They would show gory,
shocking films of accident scenes, hoping to impress the young, future drivers.
They don't do that any more, but I don't know if this is because they feel it
was not effective, or because they are concerned it is no longer socially
acceptable. . .

I think it's too dramatically different from everyday experience, so the
people watching the gory pictures tend not to identify with them, so they
really don't have much effect.

There's always the danger of being too over-the-top in safety warnings, such
that people realize how improbable or exaggerated the risks are and then fail
to pay attention to the parts that are truly relevant.
