A noise similar to an airplane engine is typical of a noisy wheel bearing. Shaking only when accelerating, more so starting from low speeds is commonly caused by a worn area inside the inner cv joint housing. Usually though you DO feel that in the steering wheel.
Didn't the alignment mechanic notice these issues on the final test drive? Besides the tires, you also must look for anything that will cause the wheels to wobble. That includes a bent wheel, debris stuck between the wheel and brake rotor, and debris stuck between the rotor and hub. A warped brake rotor can show up with different symptoms too.
