Kinetic energy and thus landing distance, is proportional to the square
of the speed. (Students need to be told this when learning to land.)

I read a statistic somewhere that if you touch-down at 50 mph, assuming

Increase to 70mph, and you need 40 something feet.

Fly her all the way into the ground, make a shallow, full stall
landing, and you'll probably survive... The real danger comes when
people place too much value on not harming the aircraft.
