Bernoulli`s Principle is what creates most of the Lift. Bernoulli`s Principle when a specific shape of an aircraft motion wings make air move slower underneath it which generates more pressure and creates lift. Lift is not so easily created without a sustainable angle of attack.
Without angle of attack, no matter the amount of thrust generated, the plane will not lift off the ground. If the angle of attack is to high for the thrust to continue generating speed then then weight will overcome lift, and the further result will be fatal.
