There was a TFR in 1980, too. The TFR is not protect the volcano, it is to
protect you. Personally, I am coming around to the opinion that they
should
just let anyone in there who wants to see it, including airplanes, as long
as they sign a waiver that they will not sue anyone in the event that they
run into each other or are killed by the volcano.

IIRC there has never been an airplane brought down by Mt. St. Helens
volcanic activity. I do know of a fellow who augured a Huey while giving
some people a sightseeing trip over heard of elk on the east slope. The all
lived...he died instantly as a piece of metal punctured his heart.
