Sending F-22s, in general, makes sense in this case given that they can operate and maneuver at higher altitudes than any other U.S. fighter. The balloon is likely soaring at well above 50,000 feet given the Pentagon’s assurance that it is high enough to not pose any hazard to commercial air traffic. This would have put it beyond the reach of F-15C/D Eagles or F-16C/D Vipers that might have been based closer by.
