Yuma Test Station: Second UFO sighting with failed theodolite measurement
On the following day, two soldiers with engineering backgrounds attempted to track the object using surveying equipment. The target moved too rapidly and erratically for theodolite measurement, disappearing within ten seconds. Unlike the previous day, the craft left no visible vapor trail during this second observation.
Background
Twenty-four hours after the initial sighting, two members of the meteorology team attempted a scientific documentation of the phenomenon. Both soldiers held engineering degrees and had positioned themselves with a theodolite instrument to capture precise measurements if the object returned.
Their opportunity materialized when the craft appeared again, exhibiting extremely rapid and erratic movement patterns. The unpredictable trajectory prevented successful triangulation or angular measurement despite their technical preparation. The observation lasted approximately ten seconds before the object disappeared across the horizon.
Notably, this second appearance lacked the intermittent vapor trail observed during the first encounter, presenting additional characteristics that complicated conventional explanations.
