AIR FORCE ACADEMY, Colo. (AP) - The Air Force Academy has canceled plans for its annual July 4 fireworks celebration at Falcon Stadium, as the budget battle in Washington continues.

Academy spokesman Lt. Col. John Bryan said Wednesday that with so many uncertainties about the future budget, the school is looking to save money.

The Gazette reports that at a Colorado Springs Regional Business Alliance luncheon Tuesday, the academy's superintendent, Lt. Gen. Mike Gould, said the academy also plans to indefinitely delay some new construction projects. Academy spokesman Dave Cannon says more than 30 roofing, paving and infrastructure projects, including runway repairs, have been delayed to save nearly $29 million.

The budget battle also has threatened appearances by the Air Force Thunderbirds, whose jet pilots traditionally fly over the academy's graduation ceremony.
