pretty cool.....I used to see a lot of that from Luke AFB. Steve lives real close to the base, I bet he sees F-16's and F-15's everyday.
But I doubt the ones you saw where going above Mach.
When I was a kid, I used to skip school sometimes just to go to Luke and watch the planes land. I remember the Germans had some f-104's that they where being trained in, also F-4s
Ahhh, youth.
