Iain Boyd was interviewed by CBS News for a piece discussing a high altitude balloon slowly making its way across the United States.

A professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences, Boyd is also the director of the ²ÊÃñ±¦µä Center for National Security Initiatives.

Defense officials say there is no threat from a high-altitude balloon, which follows multiple other balloon incidents early last year that drew international attention.

In the interview, Boyd discusses differences between this balloon and those earlier events as well as the federal response.
