If a plane stalls why doesn’t it glide through the air instead of tumbling down to earth?

It's important to know that a "stall" doesn't generally mean that the engines stopped working, but rather that the airplane is at an angle where it's no longer generating enough lift to fly.

As an extreme example, imagine if the pilot pointed the airplane to fly straight up, so the airplane is vertical to the ground. The engines can't provide enough thrust to fly straight up, so once the plane runs out of velocity, it will fall back to the ground like a rock.

In contrast, with the famous Gimli Glider, a 767 ran out of fuel due to a math error when it was fueled. It glided 50+ miles and landed safely.
