RADCAT Case Directory
  Category 9, RADAR

  Preliminary Rating: 5  


RADCAT is a revitalized special project now being conducted jointly by NICAP & Project 1947 with the help and cooperation of the original compiler of RADCAT, Martin Shough, to create a comprehensive listing of radar cases with detailed documentation from all previous catalogues, including UFOCAT and original RADCAT.

AF Pilot Sees UFO/On Radar
June 17, 1953
Iwo Jima Island

June 17, 1953; Iwo Jima Island, Japan (BBU)
2345K. An AF Pilot on round-robin flight from Yokota AFB to Iwo Jima observed an unidentified radar target 15 miles from Iwo Jima traveling 600 knots on a 35 degree bearing. Pilot called Iwo Jima and was advised that no a/c were in area. On his return trip pilot observed same object 10 miles N and 20 miles N on radar screen. Pilot reported 100 miles N later that an object appeared to follow him and that it closed within 1 mile from him and then disappeared from radar scope.

Brad Sparks:
This is just a BB Record Card and very unreliable.  Already it has two totally inconsistent times, 2345Z and 0006K (military "K" time zone) when Korean time is GMT + 9 hours ahead assuming no Daylight Savings Time.  The 2345Z time would be 0845K time.  The 0006K is supposed to be LATER not >8 hours EARLIER.  This is typical of BB sloppiness that they couldn't even convert time zones correctly. There is enough there on the Record Card that is clearly unexplainable as Anom Prop that I would list the June 18 case as a poor quality Unknown until a case file was obtained. It is difficult to see how anom prop could cause a target to approach to within 1 mile or 0.5 mile of an aircraft flying well above any inversion layer.  Even if it was an elevated layer it has to reflect off a real target on the ground and the angle would be too steep.

Jan Aldrich:
Clarification on those cards......They are from Hynek's file at CUFOS.  Some reports had complete case files others just had cards.  Since these were actual copies, not Xerox copies, I copied each one.  I sent the radar ones.
