In a nut shell, any charter operator is now exposed, their tails are trackable now. Someone like Trump & Travolta, who are high profile personalities, can probably prove that having their whereabouts published would be a valid security concern. Although, Trump didn't have his old a/c blocked, will have to see if N757AF stays trackable.
