A senior U.S. official said in response Wednesday that “despite Pakistani rhetoric to the contrary, there are no significant changes to how either side does business.”

American officials said Pakistan’s leadership has not denied the U.S. the right to use the country’s airspace, though if airspace is denied, Col. Bushey said, the U.S. has other means of surveillance.

“If we were politically unable to fly over their airspace, then we would have to come up with other means of surveillance. Obviously, aircraft is not the only means of surveillance,” he said at the conference.
