It's a datapoint and a thorough investigation would take it in to account and give it the weight it deserves. For us plebs on the sideline we don't have access to much of the information and so...

lemme, I only have access to a BAe146-300 speed card and the speeds might be a few knots off compared to an RJ85 for the same weight. That said, it would appear they were far too slow for a glide....
