Oil tankers sat low in the water just off our shores during that time.

Ask any old pilot or fisherman, they all saw them.

I think the trick was to fill the ullage in all our gas tanks. On average tanks are probably half-full, but during the crisis we all topped up, so possibly millions of gallons got sold during that period.

Plus it was an experiment in people-control. We all put up with a LOT without much protest.
