This doesn’t adds up. Landing on a roof due to sink in the pattern which required starting the motor? Too low for a BRS chute? How can you be too low for a BRS chute. You can deploy them in 1 sec from ground level. Better use a device which was designed to save your life vs relying on sheer luck. More plausible explanation is yet another case of “tunnel vision” where the pilot was focused on only one thing without realizing there are alternatives. Not blaming him without knowing the details, tunnel vision is a vicious thing that can and does happen to the best of us.
