Yes, you can often use flour two years past its "best by" date, especially white flour, but you must check for spoilage (musty smell, bugs, off-color/taste) and be aware that its quality, leavening power (gluten), and flavor might be diminished, making it better for thickening or coating than for important baked goods. Whole grain flours spoil faster due to natural oils and should be discarded sooner if they smell rancid. 

Is flour more explosive than gunpowder?

Yes, flour dust can be more explosive than gunpowder under specific industrial conditions, though gunpowder is designed to be a predictable explosive. Flour's explosive power comes from its fine particles dispersing in the air to form a combustible dust cloud, needing only a spark, while gunpowder is a pre-mixed chemical designed for rapid burning, but flour's rapid combustion (high KSt rating) can exceed some low explosives when conditions are right, making it a serious industrial hazard in food processing plants.
