It's difficult to determine, but a group of aviation enthusiasts say they caught a glimpse of a mystery aircraft earlier this month flying slowly across the Amarillo, Texas sky.
"We looked southwest and there they were," Steve Douglass, a journalist and member of the group, told FoxNews.com. "We thought they were B-2s, but when we studied our pictures, we ruled that out."
Douglass and his group, armed with cameras and binoculars, met on March 10 at the Rick Husband Amarillo International Airport. The airport is a perfect venue because it offers expansive views of Texas' big sky and a steady stream of military air traffic. On a good day, the group can see various military jets, and even the elusive F-22 Raptor.
It was a clear day, and the group was alerted to three aircraft flying across the southwest skies. Douglass estimated that the planes got within 20 miles of the group and they started taking pictures with their 300mm zoom cameras. They looked at the photos, and saw that one appeared to be a silver-grey B-2 bomber.
The prospects of spotting a B-2 bomber was exciting, and Douglass said he got home to observe his photos when he noticed the aircraft in his picture had a smooth backside. The B-2 bomber has a distinct "W"-shaped back.
"The trailing edge is wrong," Douglass shouted, according to his March 28 blog post.
Few items provoke public interest like an unidentified flying object. These stories are often attached to other theories about hidden testing bases or alien life forms. But these images have prompted some interest in the industry.
"The photos tell us more about what the mysterious stranger isn't than what it is," Bill Sweetman writes in Aviation Week, which first reported on the story. The report said that Douglass picked up some apparently related voice signals, which would indicate the aircraft had a pilot. Editors at Aviation Week reportedly say the images appear to be "something real."
"If I had to guess, I'd say we took a picture of a stealthy transport aircraft," Douglass said.
Douglass writes that he reached out to Whiteman Air Force Base in Missouri, which houses B-2s, to see if it flew any planes over Texas on that day and did not get a response.
