If his standby instruments were operable, the answer to that question is likely "yes." Having not flown a STOVL aircraft, the only part I can't speak to is whether his thrust vectoring/lift fan was in an unknown configuration, and how that plays into things. But generally out-of-control flight results from a spike in angle of attack at low speeds leading to aerodynamic stall and departure, and modern fly-by-wire aircraft are highly resistant to this.
