To get > into a private plane, today, most people show their state issued driver'license. correction: in most places, you don't need to show any identification to get into a private plane. many airports serving private planes are nothing more than a long field, and even those that are paved do not necessarily have a fence or any security guards - because there is no reason for them to have such things. it's only in those places where the government is headed by incompetent morons that insist on imposing useless restrictions which do absolutely nothing for security that you have to put up with such stupidity. we now return you to the debate on global PKI...
