Wind-ash traveling faster than the speed of sound AND light during the n
uke scene?
So apparently when a nucular detonation several hundred kilometers away happens (remember it's a 6hour drive from London-Heatrow and the cousins' house) first you're reached by the blast winds, then ash starts to fall down, then you hear the noise and finally you see the explosion itself?
How does this make any sense at all?
Plus, if they were near enough to effin get covered by ash fallout they'd be so contaminated by radiation they wouldn't last a week.
