Wow, Delta, all great questions, and I thought exactly the same......the POTUS wouldn't come to this event at this point......maybe, if we are lucky, he will cut the ribbon for the first flight.

And.....as I see the best answer to your questions.....I believe that Tony and his Staff are now trying to hold off everything that they can for as long as possible, just to make that much more of a big splash at the SHM......................
