Nothing except a helicopter goes down faster than an Gruman AA1 w/o power.
Many years ago, one got written off in South Wairarapa on an FLWOP exercise. Seems the pilots (instructor+student) both forgot to warm the engine on the way down after simulated failure at 3000 ft. Overshoot comenced at about 30ft, but the noise didn't recomence until after the aircraft hit the fence at the start of the paddock. So the exercise was a total failure.
