Not sure if they have been mentioned yet(haven't read every single post) but a couple of my most exciting memories were the demo of the "new" at the time, M1 Abrams flying down the course at 60mph over humps and bumps at Aberdeen Proving Ground and destroying every target without a miss. The next was seeing the "new" at the time A 10 Thunderbolts maneuvering around the skies of Germany chasing each other down. Man!!... anyone in sight of them would just look up and smile. Great times indeed!!
