Interesting... After seeing the pictures of trumpet structure sitting at the end of T5, it definitely looked out of place.
In hindsight, it would have been nice if the T5 architects had designed a trumpet-like flute at the end of T5 as a nod to what was once there. Such a gesture certainly wouldn't have cost the "$10M" that they claim it would have cost to restore the original trumpet and would have created an amazing lounge with a view of 4L-22R & 13L-31R. Or a bar, lounge w/couches, or who knows.
