Wings do not tilt, and the force that turns an airplane is its horizontal component of lift, not thrust.

Ah, but what causes lift? There must be a thrust somewhere.

John, when speaking of airplanes, the terms "lift" and "thrust" have specific meanings. While lift is a
force, it is not
thrust. Lift is the force on the wings that keeps the plane in the air. Thrust is the force of the engine (propeller, jet) pushing the plane through the air. This is the technical context that The Bad Aviator is using, and why he is correcting the BA.
Weight and drag are the other two components of the equations.
