“LOUVIERS (27) 17.09.2017”
Source: LOUVIERS (27) 17.09.2017
// [[T0001]] case title
The case is classified in category C.
Claim #8461 // FACTUAL CLAIM // SOURCED // 99% extraction confidence
“This case is to be classified in category “C”: lack of reliable information.”

// [[T0004]] concluding classification
The source identifies the phenomenon type as lack of reliable information.
Claim #8462 // FACTUAL CLAIM // SOURCED // 99% extraction confidence
“Phenomenon type
Lack of reliable information”

// [[T0001]] case details
The witness reported three faint lights arranged in a triangle and a dark triangular object seen against a cloud.
Claim #8463 // ATTRIBUTED CLAIM // SOURCED // 97% extraction confidence
“The witness sees 3 faint lights arranged in a triangle, which draw his attention because of their unusual appearance. The witness then sees the outline of a dark, triangular object stand out against a cloud.”

// [[T0001]] description
The observation lasted less than 10 seconds and only one testimony was collected.
Claim #8464 // FACTUAL CLAIM // SOURCED // 99% extraction confidence
“The observation lasts less than 10 seconds. Only one testimony will be collected.”
Source: LOUVIERS (27) 17.09.2017
// [[T0002]] description
The source describes the object as moving silently in a straight line through the night sky, with low-intensity lights outlining a dark triangular shape.
Claim #8465 // FACTUAL CLAIM // SOURCED // 96% extraction confidence
“Observation of the silent, straight-line passage through the night sky of three low-intensity lights outlining a dark triangular shape: lack of reliable information.”

// [[T0001]] summary
The investigator favored possible misidentifications involving Thai lanterns, civil or military aircraft, or a civil or military drone.
Claim #8466 // ATTRIBUTED CLAIM // SOURCED // 99% extraction confidence
“the hypotheses favored by the investigator are misidentifications involving Thai lanterns, civil or military aircraft, or a civil or military drone”
Source: LOUVIERS (27) 17.09.2017
// [[T0002]] investigation discussion
The Thai-lantern hypothesis was considered partly compatible with the description but not probable because the wind was blowing opposite to the UAP's trajectory.
Claim #8467 // ASSESSMENT // SOURCED // 99% extraction confidence
“However, the Thai lantern hypothesis, although partly compatible with the description, is not considered probable, given that the wind was blowing opposite to the UAP's trajectory at the time of the observation.”

// [[T0002]] Thai-lantern hypothesis
The civil-aircraft hypothesis could not be retained because the viewing angle and radar directions did not match the observation.
Claim #8468 // ASSESSMENT // SOURCED // 98% extraction confidence
“The hypothesis of a civil aircraft cannot be retained because the viewing angle from the window does not allow aircraft on the existing air route to be seen clearly, and those appearing on radar echoes are not in the correct direction.”
Source: LOUVIERS (27) 17.09.2017
// [[T0002]] aircraft hypothesis
The military-aircraft hypothesis was not considered probable because the witness would have been expected to hear engine noise and there was no confirmation of a military flight.
Claim #8469 // ASSESSMENT // SOURCED // 99% extraction confidence
“The aircraft hypothesis is therefore not considered probable.”
Source: LOUVIERS (27) 17.09.2017
// [[T0002]] aircraft hypothesis
The investigator considered a civil or military drone flight, but the absence of an authorized nearby aerial-overflight area and lack of confirmation of a drone flight tempered that possibility.
Claim #8470 // ASSESSMENT // SOURCED // 99% extraction confidence
“However, the absence of an authorized aerial overflight area (especially at night) near the observation area also tempers this possibility. In addition, there is no confirmation of a drone flight from the base.”
Source: LOUVIERS (27) 17.09.2017
// [[T0003]] drone hypothesis
The UAP's straight-line, constant-speed trajectory was not considered strange, but its appearance strongly puzzled the witness and the considered hypotheses could not explain it.
Claim #8471 // ASSESSMENT // SOURCED // 99% extraction confidence
“The UAP's trajectory presents no strangeness (straight-line, constant speed). However, the appearance of the UAP strongly puzzles the witness (3 faint lights in a triangle with a dark mass at the center), which the hypotheses considered cannot explain.”
Source: LOUVIERS (27) 17.09.2017
// [[T0003]] final assessment
The case could not be investigated further because there was no additional witness, photograph, video, or precise time information.
Claim #8472 // ASSESSMENT // SOURCED // 99% extraction confidence
“The lack of additional information (another witness, photographs, video, precise times) does not make it possible to investigate this case further.”
