This was the somewhat worrying moment a US airline passenger spotted a B-2 Stealth Bomber cruising below their plane last week (June 5).
The footage captured from a Southwest Airlines flight from Las Vegas to Chicago, which was above the skies of Colorado, shows a US military aircraft dubbed the Stealth bomber below.
One commenter online explained that: "Even flying airliners I'm surprised at how often you start to come across things.
"But one of those is absolutely a catch."
The filmer comment: "[I] just started flying again the last few years after about 20 years not flying so I wasn’t sure if it was common to see other planes."
