From Wikipedia:
“What is the highest altitude of F-22 Raptor?
Image result for how high can an f 22 raptor fly
65,000 feet
An F-22 Raptor is capable of flying 65,000 feet in the air.
At this height, it is capable of reaching higher speeds and
accelerating to these speeds faster than at sea level. Part
of the F-22 Raptor’s advantage comes from its aerodynamic
design and internal engineering advancements”.
I think the balloon (at last sighting) is higher than that. It was only noticed over Montana because for some reason it dipped down lower.
In any case, it takes about a week for a balloon to deflate.
It’s already done its work anyway, and the Biden regime and Hunter can collect their checks any time now.
