The Levelland vehicle interference cases

Beginning about 10:50 p.m. on 2 November 1957, the sheriff's office in Levelland, Texas took a sequence of calls that would define the vehicle-interference category. Pedro Saucedo and Joe Salaz reported a torpedo of flame that passed over their truck, killing engine and lights. Over the next hours, drivers at locations ringing the town — several with no possibility of contact with one another — described a glowing, egg-shaped object of enormous size sitting on or near the road, their engines dying as they approached and restarting freely once it rose. Sheriff Weir Clem, patrolling in response, reported a red glow crossing the highway. The night ended with the object gone and the town on the national wires.

The Air Force dispatched a single investigator for a single day. Blue Book's disposition attributed the reports to ball lightning or St. Elmo's fire in stormy conditions, and recorded fewer witnesses than the sheriff's log. The explanation has two standing problems on the record: area weather observations that night show overcast and mist but no electrical storm, and ball lightning as described in the literature is a phenomenon of seconds and centimeters, not minutes and road-spanning size — and no mechanism for it stalling engines is established.

The Levelland reports arrived the week after Sputnik 2 launched, at the peak of a national wave, and they made engine-stoppage a fixture of the phenomenon's grammar. The case is the standard example of a disposition issued faster than its evidence could support — which is precisely why the disposition is recorded here as given, alongside what the weather records say.
