No reason why they would be, if proper precautions were taken... and I
think the problem was understood by that time.
The reason beryllium isn't more widely used for aerospace structures today
is not so much that it's toxic as that it's *brittle*, for fundamental
reasons of crystal structure which are not fixable. (It isn't because
people didn't try...) Aerospace customers put up with materials which
need all kinds of obnoxious manufacturing procedures. Beryllium is not
that much worse than some other things in terms of the hassles involved;
the problem is that it just doesn't work very well for general-purpose
