Does anyone know if there are any longer term (5 years or greater) rough statistics on the number of "bail-outs"? A long shot probably since many probably go unreported. I'm doing a class on safety and survival and thought it might be good to shed some light on how often or not bailouts or self-rescue really happen. Also helpful would be a breakdown of ladder-bail or similar and those using personal self-rescue systems, engineered or otherwise. Even better would be the type of fire and building involved. Not asking for much am I?

Like I said, a long shot, but you never know who's collected some obscure data!
