I always understood the T/O data to include the use of the stopway, or in this case, the EMAS. In short, I fealt that C.W. was a departure not to be aborted unless a wing fell off..............
Installing EMAS would actually do more damage to an airframe at several airports rather than the grass at the end. It's too expensive and very impractical for many airports. If the ASA 700 would have used the EMAS at SAV, it would have torn some stuff up good (gear doors, struts, belly skin, etc.). With the grass at the end, it probably just needed to be hosed off and given an inspection with few, if any, broken parts as a result............
