An airplane that took off from Oslo on a clear day, heading west, would be going into a headwind of about 834.9 km/hr (= about 519 mph). Thus, it would need to travel at least the speed of a fast passenger jetliner to make even a few miles of headway.
In a sense, that would be true relative to a fixed, external to the Earth reference point (considering only the Earth's rotations speed, and I'm assuming his numbers are correct). Fortunately, it's relative to an Earth bound reference point he needs to be moving, and the Earth's surface is moving 519 mph east (relative to that same fixed, external to the Earth reference point).
