The difference between making it and not making it on an unintentional flaps up take off is the initial rotation rate and initial deck angle. Most any aircraft will take off with flaps up if the runway is long enough and clean stall attitude isn't exceeded providing tires don't blow first. A friend of mine did one in a 737 out of LAX many years ago and made it after initial stick shaker with no problem. If they look at the initial deck angles of both flights the FDR will tell the story very quickly.
