Wow. One of these times President Trump will walk outside and work the crowd. Surprised he hasn’t already.
He has spoken to overflow rooms and perhaps a time or two to those outside hangars.
However, I don’t think the Secret Service would approve of him exposing himself in such an uncontrollable scenario.
I think it’s just fine that he provides for closed circuit big screens and acknowledges those who don’t make it inside to enjoy the better location.
