Police say a spaceship - or at least a fiberglass and metal version of one - is missing in Roswell, the New Mexico town that still stirs debate about extraterrestrials seven decades after the 1947 crash of a flying object.

Police say the model flying saucer was stolen from the UFO Museum in Roswell early Saturday and remained missing Tuesday.

Some on social media suggested in jest that “men in black” or “aliens” were to blame. But police say surveillance video shows three thiefs hauled away the spaceship in a pickup truck.

The spaceship is a fixture in downtown Roswell, where it was long mounted outside the UFO museum before a recent snowstorm damaged it. Police say the suspects stole it from behind the museum, where it was being stored.
