The rear part of an airliner can hit the ground if the pilot pulls too
much on the elevators control. I have been tolled that this kind of
problem has occurred on one prototype from Airbus. And it has probably
also happened to other aircrafts.

A small airplane can probably have a higher angle of attack before its
tail hits the ground. But I don't know if the wing will stall before
or not.
