For an airplane to take flight two special forces are required Thrust and Lift. Thrust is the forward motion caused by the engines. Enough Thrust must be generated to overcome the force of drag from the friction that is created while moving through the air. That's why airplanes are shaped like they are so their form is as aerodynamic as possible to in order to reduce drag and maximize the thrust provided by the engines. For an airplane to take flight thrust must be equal or greater than drag.
The other necessary force needed is lift. Lift is generated by the airplane wings. The wings are shaped and tilted in such way that when air moves across the wings an upward force is generated. This will lift the airplane into the sky.
from your post i have learnt you need thrust and lift for the air planes to lift of I wonder how they can hold so much weight.
