ATC unions have blocked automation for 30 years, but it was not until lately
that the catastrophic events generated by ATC seperation error became the
majority of the total body count.

Could we be more specific? Air traffic separation incidents
resulting in a body count implies aircraft collisions. The
only one I can recall is a runway incursion error at LAX a
few years ago. Are there others?
