DENVER, Colo. -

Delta Flight 1500 from Detroit to Denver International Airport was forced to land Friday night because of a safety concern, per NBC's 9 News.

The airplane landed in a remote location of the Denver airfield because of a security threat. One passenger says that all 151 passengers were taken off the plane and bussed to the terminal without permission to take anything from the overhead bin upon exiting.

"We were about 1,000 feet off the ground and that said that we were going to change the location outside because they found a suspicious note in the back of the plane. The stewardess did, supposedly," said passenger Tone Sevy. "They just pulled everybody off the plane, before we got off the plane they sprayed it with water for a few seconds."

FBI agents interviewed passengers at a secure location at DIA.

Delta Spokesperson Russell Cason said that the 151-passenger plane landed safely at 4:40 p.m. and was directed to a remote location. The passengers were cleared to return to the plane to get their personal belongings after about two hours of waiting. They are now being taken by bus to the terminal.

"We came down very fast, we went from an altitude of 30,000 and we jumped down quick," Sevy said. He said that the atmosphere was pretty calm as the plane landed and evacuated.
