In Branson's case, 'more money than sense' springs to mind. But of course if and when this pipe dream of his ever comes to fruition, there will be plenty of takers, like him, with 'more money than sense'. He seems completely unphased by the fact that one person has died, and another one has been seriously injured in this expedition. The massaging of egos must be a powerful magnet.

Why anyone would want to ponce around in space with no discernible destination other than to circumnavigate the globe, is completely beyond me anyway.
