... "While I was working on this article, a well-known aviation journalist said to me that blaming the Potomac River midair collision on an interaction between complex systems is a copout that allows those responsible for the accident to walk free and prevents corrective actions from being taken." (Also my post was direct quote from the article. I understand what you are trying to do. Because of that people already died and this will be repeated. I have zero tolerance for that BS. You should too.)
