Are they still claiming that they will be displaying...
...elsewhere this week? If so, and if this is as wildly unrealistic/impossible/fanciful/incredible as people here seem to think it is, then what would you say to somebody wooed to one of these airshows and convinced to part with cash on the promise that the Vulcan will display, unless something unforseen prevents it? And if they went to the police, alleging that they had been defrauded out of their gate money because TVOC knew or should have known a week in advance that they were never going to be allowed to display as long as they had holes in their backsides, what defence would you mount for TVOC?
