I remember a little over a year ago, I brought up a thread called "acceptable loss's." You take an average field on any given day and you may have a crash or two in relation to the total amount of flights that day.

We had an airshow over a two day period and i recall we had 18 total loss's out of 350something flights. Not sure if thats good or bad but was just for information. Be good for statistic purposes to keep track.
