Military aviator here, not commercial.

Runaway trim is an emergency procedure and usually requires pulling a circuit breaker to stop the condition. Using brute force on a control surface at 200+ knots would require the Hulk to overcome.

At speed, control surfaces do not move a great deal (5-10 degrees as an example) and are hydraulically controlled. So the short answer is no, human strength cannot overcome the force on the surface.

Modern aircraft are fly-by-wire. No manual cables. You are fighting a computer override which would require disabling the system.

What about fly by wire aircraft? Is the computer system nullifying the pilot commands?

Season 1 Episode 7—Dr. David Banner attempts to land a 747 only to find he must partially transform, calling upon the strength of the Hulk to overcome a damaged hydraulic system.
