That's not exactly true. Some fighter and fighter-trainer jets, such as the F-5 (a light supersonic fighter with some strike capability) and the T-38 (a related trainer), have multiple examples in private hands in the US right now. They are very expensive to purchase, of course, and almost as expensive to maintain - thoroughbreds are a pauper's diversion by comparison - but that's not the same as saying it is impossible to own one, and depending on the specific mark of Harrier in question, I wouldn't necessarily see it as unreasonable to believe Pepsico could fulfill that claim.
