Steve Suffet here. My wife Marilyn, my daughter Lilit, and I were all far from Lower Manhattan at the time of the disaster. We're OK.
I've heard from Eric Levine, Ray Korona, Joel Landy, Jessica Feinbloom, Evy Mayer, and Joy Bennett, and all are alive and well. I presume Alison Kelley is safe as well, as she was at work in Brooklyn, although I haven't spoken to her.
