I suppose anything is possible, but I have a rather vivid memory of flying in the back seat of a FBW fighter and watching ball lightning dance along the canopy. OK, perhaps mil-spec stuff is better EMP protected than civilian aircraft, but after watching that it sort of begged credibility that a cellphone signal could cause problems.
