You keep saying millions of dollars will have been wasted. However consider an other option where it turns out to be a problem with more airplanes and hundreds of of lives 'will be wasted'. Some countries take a more precautionary approach to risk than others where there is uncertainty, and I, personally, am happy to live somewhere that is willing to take the decision to prevent possible harm to human life instead of possible harm to (a relatively small section of) the economy, where there is uncertainty.
