I don't doubt that somebody cranked it over in their turn, but as Aaron said, keeping it low and fast over the runway is hard to do in this airplane. Within a few feet of getting off the ground you're trimming down pretty quickly, and I don't think you could trim the thing fast enough to keep it 50' off the ground for 10,000' of runway, especially considering that with 10 people on board and with a full T/O you'll rotate within the first few thousand feet (flex takeoff settings aren't allowed at Chicago due to the crossing restriction). Also, you've got two options in this thing for rotation; slow which is usually pretty smooth, or quick, which rips the airplane off the ground when you do so.
But, relating to that, is the big altitude swap is the climb profile for Chicago. Climbing at Vfs or maybe 180 knots will seem like you're going straight up in this thing, but that's the climb profile in order to meet the crossing restrictions out of Chicago.
To tell you the truth this doesn't sound like a pilot flying the airplane, but instead the autopilot, the steep bank angles (though not 45 degrees) for short turns, the high pitch attitudes to capture a speed, all while doing it abruptly is exactly how the autopilot operates on this aircraft.
