TK951 with its closed throttles and trimming pitch for altitude to stay on GS didn't work out so good. If the pitch trim had been used for speed instead of altitude, the closed throttles would have made it sink below GS sooner, and given the pilots, "Too Low, Glideslope" in time to make a recovery with the trim properly set for the speed.
Cute, Trent, but until it's planing through the air, it's not an airplane.
