P.Pilcher
Nothing at all to do with it. In fact generally pilots (commercial pilots) do not make good businessmen. And before I get shot down, my rationale is that they prefer flying an aircraft rather than a desk. And PM does not hold an ATPL, his flying is restricted to recreational only.
The reason is quite simply that despite all his failings in man management (highlighted here in many past threads) he is just a very good businessman and tighter than a d***s a**e! And employs managers who allow him to run the whole outfit like a one-man band.
By buying his aircraft cheaply he can afford to have lower utilisation than say RYR and EZY. And he has an excellent engineering setup.
