First question. Is this given to trump personally , or is it given to the president? and would be the property of the US after trump leaves office?
Second, it can never be used as a presidential plane because of the obvious security concerns. This lane was in possession and control of a foreign goverment. Even the current Air Force one, if it was under the control of a foreign goverment, would not be able to be of use again as a presidential plane, because even after you did the most extensive sweep, you still cant say with absolute certainty that it is 100% secure.
