Why? For pity's sake, why?
There are any number of acrobatic aircraft available should you want to indulge in such antics, why chose a Citation?
Really there is no excuse today for the cowboys to be allowed this sort of indulgence. Companies should have procedures in place to weed out these pilots before they get a chance to kill themselves and others.
If they happen to be the owner of the company then pilots should be strong enough to refuse to work there. If they are not then they are as responsible for what happens as the owner.
