Yes it was not all the same..Sometimes one plane, sometimes 3..Sometime Choppers..
But cut backs in the military, they arent doing them anymore
It has to do with available aircraft and not budgetary at all. Military aircraft are on a budget but more importantly on a schedule.
Flyovers are available from individual flying teams as well. I saw P-51s over Road America. The government doesn't fly P-51s anymore obviously.
Check out the yearly fly-in or military weekend at Mitchell Field each year. If you go on Sunday many of the aircraft have to go back to their originating units. You might see an F/A-18 in a military takeoff and climb or an A-10 fly circles around the crowd. F-117s are eerie and quiet and C-5s look like whole city blocks getting airborne.
You can further check out military aircraft at a range near Wisconsin Rapids on bombing runs, don't worry, their "ordnance" is long released before you see them.
Many Wisconsin hunters have enjoyed the A-10 and F-16 flyovers in Black River Falls for years. I agree it's impressive at the game but if you like that sort of thing it can still be enjoyed.
