Did the chicken survive the firewall?

The forty-year debate about the final state of an evaporating black hole was recently reinvigorated by the suggestion that if unitarity is preserved, the black hole horizon develops a “firewall” which a) affects strongly any matter that crosses it and b) erases any information that such matter may carry about the outside world. We present evidence that neither a) nor b) is true for a firewall within flat spacetime quantum field theory, arguing that the same holds for sufficiently young gravitational firewalls. A firewall’s prospective capability to resolve the information loss paradox must hinge on its detailed gravitational structure, presently poorly understood.
