ACUFO:

ACUFO is my comprehensive catalog of cases of encounters between aircraft and UFOs, whether they are “explained” or “unexplained”.

The ACUFO catalog is made of case files with a case number, summary, quantitative information (date, location, number of witnesses...), classifications, all sources mentioning the case with their references, a discussion of the case in order to evaluate its causes, and a history of the changes made to the file.

Iwo Jima, Japan, on March 26, 1945:

Case number:

ACUFO-1945-03-26-IWOJIMA-1

Summary:

Circa 1999, U.S. ufologist Jan Aldrich published on his historical ufology Website Project 1947, an extract from the March 1945 Intelligence and Operations section of the 549th Night Fighter Squadron Unit History, including this:

Combat Air Patrols were flown on the 22nd, 24th, 26th, 28th and 30 March. On 26 March Lieutenant Calvin P. Lamb, Pilot, Lieutenant James G. Holmes, Radar Observer, and Sergeant John W. McIsaac, Gunner, saw what they described as lights on an airborne object. The lights followed them through a few turns but turned away as the crew orbited north of Iwo Jima. A chase was made, with slight radar contact on the airborne set, and then the object pulled out of sight.

An extract from the March 1945 INTELLIGENCE AND OPERATIONS section of the 549th Night Fighter Squadron Unit History:

Combat Air Patrols were flown on the 22nd, 24th, 26th, 28th and 30 March. On 26 March Lieutenant Calvin P. Lamb, Pilot, Lieutenant James G. Holmes, Radar Observer, and Sergeant John W. McIsaac, Gunner, saw what they described as lights on an airborne object. The lights followed them through a few turns but turned away as the crew orbited north of Iwo Jima. A chase was made, with slight radar contact on the airborne set, and then the object pulled out of sight. The similar lighted object was again seen the next night of patrol by Lieutenant William F. Sill, Pilot, Flight Officer George W. Hayden, Radar Observer, and Private First Class William Brasvell, Gunner.

NOTE: There were many reports of Japanese planes which dropped aluminum “windows” (i.e. aluminum foil strips) at night when chased by U.S. aircraft. This foil confused radar signals. However, in some of the chases recounted in this unit history, this does not seem to have been the case. Also, the “bogies” seem to have been able to accelerate to much higher speeds to get away from the night fighters. Most Japanese night flight operations around Iwo Jima seemed to be “lurking” intelligence gathering missions. US Pilots reported aircraft like the “Betty” (Mitsubishi G4M long-range medium bomber) escorting but not firing on bombers making their run on Iwo Jima and the surrounding Islands at night.-- J.L.A.

JAPAN, Iwo Jima

During the night, the 3 members of the crew of a combat plane (549th NFS) observed, with a faint return to the on-board radar, several lights following the plane, making several turns. (PROJECT ACUFOE, Catalog 1999, Dominique Weinstein)

P-61-B, 549th Night Fighter Squadron (NFS), Gunner saw lights on an airborne object that followed them through turns. P-61 gave chase, with a slight radar contact. Object pulled out of sight. (549th NFS Unit History for March 1945)

Iwo Jima, Japan MIR

At night, a crew of a P-61B from the 549th Night Fighter Squadron, including Lt. Calvin P. Lamb (pilot), Lt. James G. Holmes (radar observer) and Sgt. John W. Mcisaac (gunner) saw several lights following their plane through a few turns, but turning away as the pilot orbited north of Iwo Jima. A chase was made, with a slight radar contact on the airborne set and then the object was pulled out of sight.

And in March, 1945, according to the 549th Night Fighter Squadron Unit History:

Combat Air Patrols were flown on the 22nd, 24th, 26th, 28th and 30 March. On 26 March Lieutenant Calvin P. Lamb, Pilot, Lieutenant James G. Holmes, Radar Observer, and Sergeant John W. McIsaac, Gunner, saw what they described as lights on an airborne object. The lights followed them through a few turns but turned away as the crew orbited north of Iwo Jima.

Sill, Pilot, Flight Officer George W. Hayden, Radar Observer, and Private First Class William Brasvell, Gunner.

[Ref. get1:] GEORGE M. EBERHART:

March 26 - During an air operation, Lieut. Calvin P. Lamb (pilot), Lieut. James G. Holmes (radar observer), and Sgt. John W. McIsaac (gunner) notice lights on an airborne object. The lights follow them through a few turns but move away as the crew orbits north of Iwo Jima, Japan. They give chase, obtaining a slight target on the aircraft radar, then the object pulls out of sight. A similar lighted object is again seen March 28 by Lieut. William F. Sill (pilot), Flight Officer George W. Hayden (radar observer), and PFC William Brasvell (gunner). (Project 1947, “UFO Reports, 1945”)

Aircraft information:

The Northrop P-61 “Black Widow” was a high performance American night fighter plane used in WWII.

It was twin-engined, with a maximum speed of 589 km/h, 3,060 km range. The crew was of three men.

It was equipped with onboard radar and armed with 4 Hispano 20 mm cannons in the fuselage and 4 Browning M2 12.7 mm machine guns in the remotely controlled upper turret.

Map.

549th Night Fighter Squadron was constituted on April 19, 1944, activated on May 1, 1944, and flew night fighter missions from South Field, Iwo Jima against the Japanese from March 22, 1945 to August 5, 1945.

From 1944 to 1945 they operated P-61 “Black Widow” night fighters.

I found pilot Calvin P. Lamb in the newspaper Herald and News, Klamath Falls, Oregon, for July 8, 1945, in this note: “Iwo Jima - Calvin P. Lamb, 22, of Klamath Falls, pilot in a VII Fighter Command night fighter squadron, has been promoted to first lieutenant.”

I found radar observer, Lieutenant James G. Holmes, in a 1955 “Army, Navy, Air Force Journal & Register” as still in the electronic warfare of the US Air Forces.

I found no information about the gunner, Sgt. John W. McIsaac.

The report is typical of many “Foo-Fighters” reports in Europe and on the Pacific theater in 1943-1945. We have the UFO following even during evasive maneuvers, but not attacking the plane.

Evaluation:

Possible extraterrestrial craft.
