On the night of 2–3 November 1957 fifteen people rang the police of this Texas town within a few hours, all with the same account: a glowing object had settled onto the road ahead of them, their engine had died and their headlights had gone out, and when the object lifted away the engine started again on its own. They called independently, from points all around the town, and two of them were the sheriff and a patrolman. The US Air Force's Project Blue Book closed the case in two days, attributing it to ball lightning in a thunderstorm; the weather record for that night shows no storm. Levelland survives in the literature as the densest of the "vehicle interference" cases — an episode where what matters is not the shape of the object but what happened to the engines.

Tremonton and the Newhouse Film

On 2 July 1952 Navy chief petty officer Delbert Newhouse was driving through Utah with his family, stopped, and filmed a dozen bright objects moving erratically high in the sky. Newhouse was a Navy photographer with thousands of hours behind a camera, which is what made the film matter. The Navy laboratory at Anacostia measured the brightness frame by frame and concluded the objects were neither aircraft nor birds. The Robertson Panel revisited it in 1953 and said: seagulls. Newhouse maintained to the end that before he got the camera out he had seen the objects closer, and that they were discs. The film sits in the archives as a case where the experts differed not over the data but over how to read it.
