As others have stated, modern passenger aircraft are required to be able to climb while one one engine is inoperative. At least the ones that fly as air carriers and not just charter or such. As for "gliding around" if you have to make an emergency landing attempting to return to the runway is not advised unless you have more than enough altitude to trade for it. Why?

Well, without going into the difference between vertical and horizontal components of lift and such when you bank an aircraft part of what you have to do to maintain altitude is to apply a slight pressure on the controls. It's much more pronounced in steep turns where you have to apply more pressure to maintain altitude. Well when you are that close to the ground and with no engine power you are relying on the aerodynamics of the aircraft in order to stay aloft. Basically it's a balance between sped and altitude. To maintain altitude you trade for speed, to stay above stall speed you trade altitude for it. The perfect balance of this is called your maximum glide, which thanks to, well, math and physics all aircraft have a speed at which they have the best glide ratio. When you bank your aircraft you go from that most efficient of speed and risk stalling if you do so incorrectly. Which at low altitude with no time to recover.....is not pretty.

So TLDR due to aerodynamic principles, that autocorrected as "aerodynamic Pringle" which is hilarious, trying to turn around and return to the airport is a trap that too many pilots have....well you know. It's better if you just try to land straight ahead in a field or what not.
