The mystery jets that were spotted over Amarillo, Texas, and Wichita, Kan. earlier this year are in fact Northrop Grumman B-2 Spirit stealth bombers on a training sortie, military sources told USNI News on Monday.

“The Amarillo jets were B-2 training sorties,” an U.S. Air Force official with direct knowledge of the incident told USNI News on Monday.

The jets were enroute to the Utah Test and Training Range to practice dropping bombs after a brief delay at the Melrose Air Force Range in New Mexico.

Flying out of Whiteman Air Force Base, Mo., the B-2s would likely have navigated via Amarillo to get to Melrose Range.

“The Kansas picture is likely any number of training sorties flown around Kansas and Missouri,” the official added.

Whiteman, the home station of the B-2 fleet, is just outside of Kansas City near the border between Kansas and Missouri.

Earlier reporting that suggested that the images showed a thus far unknown type of triangular aircraft were mistaken due to the poor resolution of the photos.

The triangular planform on apparent display in those shots is the result of an optical illusion that obscured the trailing edge of the B-2s design.

“Given the resolution of this photo, we can’t even tell if it is a military

aircraft, much less an Air Force one,” Air Force spokeswoman Jennifer Cassidy told USNI News on April 21.
