The fact that neither aircraft had a TCAS warning was a very significant
contributor to the accident. Given that both aircraft were virtually brand
new, this raises a lot of questions.

I read that the major weakness of TCAS is that they do not perform very well for
nearly head on flight paths. True? I don't know. I just read it, somewhere.
