CALHAN, Colo.—It's a bird. It's a plane. No, it's a blimp that was seen hovering over Calhan in eastern Colorado.

Witnesses say they were baffled when they saw a blimp the size of a truck on the Eastern Plains near Colorado Springs, surrounded by about 30 vehicles.

According to KKTV-TV (, an unidentified local company said the helium balloon is being tested for use as part of a surveillance system.

The owner tells the station they are developing the aircraft for government agencies and large corporations who need a surveillance system to cover and keep large areas secure.
