AI-Generated Summary
A BOAC Airlines flight reported a space vehicle re-entry over the Pacific on April 9, 1964. ATIC concluded the sighting was likely a meteor rather than the Explorer IX satellite due to trajectory inconsistencies.
On April 9, 1964, at 1622Z, a BOAC Airlines flight reported observing a space vehicle re-entry at coordinates 35.50N 161.00E. The object was described as moving from East to West at a 45-degree angle of elevation. The report noted that the object appeared to split apart upon re-entry. The incident was documented under Project 10073 and processed via a CIIRVIS report. Subsequent analysis by the Air Technical Intelligence Center (ATIC) suggested that the sighting was likely a meteor observation. The conclusion was based on the fact that the reported westerly trajectory was inconsistent with the known decay and reentry motion of the Explorer IX satellite, which had also decayed on April 9. Due to the lack of duration data and the conflicting trajectory, the official assessment concluded there was insufficient data for a firm evaluation.
Explorer IX decayed on 9 Apr. Entry reported to be westerly, contrary to reentry motion. Sighting more likely to be meteor observation.

Official Assessment
Explorer IX decayed on 9 Apr. Entry reported to be westerly, contrary to reentry motion. Sighting more likely to be meteor observation. Duration omitted. Insufficient data for firm evaluation.
The sighting was likely a meteor observation rather than the reported space reentry, as the reported westerly trajectory contradicted the expected reentry motion of Explorer IX.
