TCAS only works with both transponders working. One was not working.

YOU........don't know that!

Quite right. I don't personally know whether the transponder was working
or not.

I should have said that it was reported to have ceased transmitting before
the collision, and started transmitting again after the collision. This
was part of a statement from a Brazilian Air Force representative in a news
conference. The BAF is heading the investigation into the accident. It was
one of the reasons given for holding the passports of the US pilots.
