TO: Air Technical Intelligence Center (AFCIN-{54g)
Wright-Patterson AFB, Ohio

The following supplemental information and evidence is forwarded for
further consideration and analysis in connection with the unidentified
explosion in the air over Ras Tanura, Saudi Arabia, on Thursday, 23 Feb)
1961, as reported by Major James W. Green, CO, 21st Weather Sq, Det 12,
this station, on 24 Feb 1961:

a. Photo Ce

(1) Still photograph taken by observer in boat on Half Moon Bay,

iacaie 0,10 E., latitude 26.05 Ne
Smoke formation resulting from flash explosion followed by

series a minor consecutive explosions.
(b) Two prints, Negative unobtainable.
(2) Type and make of camera: AGFA-ISOLETT-120-2}x2}.
(3) Type focal length and make of lens: 1:4.5 - 85 MM AGFA.
(4) Brand and type of film: Kodak Verichrome Pan.
(5) Shutter speed used: 1/100.
(6) Lens opening used: F-22.
(7) No filter used,
(8) Solid stand used: None, Held in boat, trolling slowly. /
(9) No panning used.

(10) Camera pointing relative to true North, and angle to ground
(water), North 45°,

b. Material.

Five fragments (one metallic and 4 charcoal-like), picked up by
another observer on South Pier of Aramco refinery at Ras Tanura, Saudi
Arabia, reported falling approximately 12 minutes after last explosion

heard. Fragments were turned in to Aramco officials who had tests run
on the metal (fresh break) which they reported indicated presence of
silver and highly magnetic with very slight radioactivity.

c. Additional Information.

Short flame, white smoke, and series of five consecutive explosions,
very high in altitude, were reported by several observers at the Aramco
compound and at this station. In one instance only was an object thought
to be seen, very small, just before the explosion, and one observer be-
lieved he saw a waterspout off the shore as if caused by a falling body
shortly after the explosion.
