CONVENTIONAL EXPLANATIONS CONSIDEREDTESTED FIRST
CHECKFor sighting 19, the responsible air-force assessment included a possible Soviet jet aircraft. [19]Conventional
CHECKFor sighting 20, the supplied report discusses radar or radiation phenomena, detection failure, and a jet-type aircraft as possible explanations. [20]Conventional
CHECKFor sighting 620, a false radar echo remained possible even though helicopter, balloon, and Venus explanations were rejected or considered unlikely. [620]Conventional
CHECKFor sighting 11, the packet supplies no settled conventional explanation; the radar and visual reports therefore remain unresolved rather than demonstrating extraordinary performance. [11]Conventional
CHECKFor sighting 18, the packet supplies no established conventional explanation and does not independently verify the memorandum's corroboration claim. [18]Conventional
CHECKFor sighting 238, the radar correlation itself was treated cautiously, so the visual account and radar track should not be treated as conclusively causally linked. [238]Conventional
CHECKFor sighting 14, the reported photographic record is too blurred to identify the object, limiting its value as sensor evidence. [14]Conventional
WHAT REMAINS UNKNOWNUNRESOLVED
?The packet does not provide raw radar data, radar recordings, calibration information, plots, or full contemporaneous investigative files for the leading cases. [18, 238, 620, 11]Unknown
?The packet does not give precise witness counts for several leading cases, especially 238, 620, and 11, and does not fully establish whether all reported witnesses observed the same object independently. [238, 620, 11]Unknown
?The corroborating sources referred to in sighting 18's memorandum are not identified in the supplied summary. [18]Unknown
?The packet does not allow a reliable comparison of the actual source quality of the historical accounts behind sightings 11 and 18 beyond their stated document tiers and attributions. [11, 18]Unknown
?No leading case has a complete, independently confirmed combination of visual evidence, positive sensor data, preserved raw records, and a documented investigation that excludes ordinary causes. [238, 620, 11, 18]Unknown
?Many official GEIPAN cases are unresolved because of limited information rather than because an extraordinary interpretation was demonstrated. [62, 620, 238, 644, 675]Unknown
?Whether the radar track in sighting 238 represented the same phenomenon seen by the AF3532 crew. [238]Unknown
?Whether the radar echo in sighting 620 was a genuine target, a false echo, or an unrelated event. [620]Unknown
?Whether the many reported witnesses in sighting 11 independently observed the same object and whether the radar lock-on was technically documented. [11]Unknown
?What specific confirming sources were behind the memorandum's corroboration statement in sighting 18. [18]Unknown
?Whether the cases' unusual motion reports reflect actual kinematics or limitations of distance, angular-size, timing, and observation geometry; the packet does not provide enough quantitative data to decide this. [238, 620, 11, 18]Unknown
?Whether any of the leading cases has a conventional explanation that was excluded rather than merely left unconfirmed. [238, 620, 11, 18]Unknown
