Thanks everyone for all the wonderful posts. I don't know why exactly but I just love aircraft. To this day, everytime I hear one flying over I have to stop and look to the skies. I think it started when I was about 6 living in South Dakota and got to see an X-15 in person.
Another one I haven't seen mentioned is the Boeing AH-64 Apache. Another bad a$$ aircraft.
Around '87 when I was at ISU, I went to hear a SR-71 pilot speak. Can't remember the name of the hall but I think it was the old EE lecture hall. It was wonderful. So many stories and so much information. One video he played was from the cockpit. Airspeed indicator displayed Mach 3 and he was backing off of the throttle. Amazing aircraft for the time and probably in my top 5. Another interesting fact he discussed was at takeoff the plane only carried minimal fuel because of leaks through the titanium skin. It wasn't until cruising speed was reached and the skin expanded due to high temperatures that they refueled in midair.
At the airshow I mentioned in my original post, in addition to the A-10, they also had a C-5 Galaxy on the ground, F-16 Thunderbird demonstration, Multiple B-1 flyovers (high speed with wings in fully swept configuration, dip wing salute, others). Great show. Just can't remember the specific year.
