A B-24 Liberator, Up Close and Personal: German Photographs of a Downed B-24 in Holland – II

This page presents the 15 pictures of Tell Me More in Luftgaukommando Report KU 1679.

By scrolling down the post from top to bottom, you’ll first see images of the two pages in the KU Report listing the captions of the photos.

This is followed by verbatim transcriptions of the entire block of text on those two pages. Each German-language caption is followed by its English-language equivalent, in italics.

Then, scrolling down through all the pictures you’ll see that each photo has its pertinent caption – in both German and English – beneath it. The English-language translations are presented in italics.

Importantly, the images and their captions are not presented in the same numerical order as in the KU Report. Instead, I’ve arranged them to appear as if you were walking along and moving through the plane, from front to rear. I’ve also added some comments below the German-English paired translations.

Picture 6 View of the weapon stand [dorsal turret] top of the fuselage, antenna arrangement according to the control unit:
a) Rear-view mirror for gunner on fuselage top
b) Revi N 6A

Comments: An excellent view of the top of the rear fuselage. Note the furrows created by the impact of the starboard landing gear tire and fuselage bottom. These extend only a very short distance behind the aircraft into the adjoining field, implying a very abrupt stop.

The dorsal turret is probably the Martin A-3C version as opposed to A-3D, the latter of which commenced with Block H-25 Liberators. Ironically, the German technical analyst referred to the turret gunsight as a “Revi N 6 A”. (Revi?!)

More intriguingly – at least, as described in the caption – are two circular rear-view mirrors mounted within opposite sides of the turret, each located between the .50 caliber machine gun and turret bubble. The starboard inner turret mirror is also visible in photograph number 7.

Notice that the cover of the starboard emergency life raft compartment has been detached from the fuselage.

Picture 10 Plexiglass covering of the nose spire [sic] with painted [markings]
a) Crack of the plexiglass was zigzagged by bilateral perforation of the plexiglass halves and by pulling in a wire.

Comments: Here’s a different way of looking at things: The photographer stood atop the front fuselage of Tell Me More, and pointing his camera down, photographed the top of the “dome” of the Emerson A-15 nose turret. Immediately apparent are numbers denoting the rotational azimuth of the turret – in gradations of 15 degrees relative to the fuselage center line – engraved or etched into the plexiglass. The overwhelming majority of photographs of the Emerson A-15 turret, where the turret is seen from the side, naturally don’t show this feature.

(Did the turret dome of the CAC / Motor Products tail turret have a similar azimuth scale?)

______________________________

Bild 9 Bugturm mit Panzerglasscheibe und Antrieb.

Picture 9 Nose spire [sic] with armored glass pane and drive.

Comments: Another view of the A-15 turret. Immediately apparent are the pane of armored glass and elevation drives for the guns. There’s a small mystery here: How was the turret dome shattered? Flak? Fighters? During the plane’s landing?

______________________________

Comments: An excellent side view of an Emerson A-15 turret, albeit not from the KU Report. Instead, from Air Force Photo 53584AC / A12599. This picture illustrates an interesting aspect of the general design of the A-15, as opposed to the structure of dorsal aircraft turrets: The guns are located well below the gunner’s head and torso.

Caption: “ENGLAND – S/Sgt. Edward J. Mickey, a B-24 nose turret gunner, of Kingston, Pa., has 30 missions to his credit and holds the Distinguished Flying Cross and the Air Medal with 3 Oak Leaf Clusters. (53584AC / A12599)”

Here’s an interesting video (at the website of Hugh Fenlon) of an Emerson A-15 in operation, albeit not (!) in a B-24.

Bild 11 Blick in rückwärtigen Kabinenabschnitt mit MK-Kugel und Rumpfseitenständen.

Picture 11 View in the rear cabin section with machine-gun bullets and [trunk] sides

Comments: Fuselage interior, looking forward. This image provides an excellent view of the waist gun opening covers in their stowed positions, and, the location of oxygen bottles. The wind blast deflector for the port gun can be seen just ahead of the open waist window. These are the original “open” style B-24 waist gun positions that are neither staggered nor enclosed. According to Alan Blue’s book, that modification only commenced with Block H-20 Liberators.

______________________________

There ends the tail – literally (ahem! – pardon the pun!), and figuratively – of Tell Me More. The photos tell the story of a single B-24 Liberator – of very, very many – that was lost in the air war against Germany in the Second World War.

Certainly every man in the plane’s crew certainly had his own, much more human story, as well: Of attempted evasion, eventual capture, and ultimately liberation and freedom. I have no way of knowing if in the decades since 1945 those stories were recorded and preserved – especially as suggested by the inscription on the tombstone of Lt. Robert Willson – but it would be nice to think they have been.

So, let this collection of photos stand as a symbol of a past that should not be forgotten.

Air District Post Office Brussels

Investigation Report No 5 / 2021

On 2 March 1944 at 2330 a Liberator had been shot down by anti-aircraft over Fienvillers (8 km southwest of Doullens). Two members of the crew had been captured. The plane was equipped as sabotage material-carrier and therefore very seriously damaged.

The type markings of the plane were as follows: B 24 D, Serial No. 42-63792. This plane was equipped with remarkable radio equipment. There were aerials on both sides of the front of the fuselage as pictures 1 and 2 show. Further, there was the following radio equipment on board, the greatest part of which has been sent by messenger to the Ministry of the Air Dorces GL C-Rue.

1. RT-3 / APN-1
27 Volt
D.C. N.X.S. – 2424
1341 C.R.V.

2. RT-7 / APN-1
110 DB / 25
N.X. – 23763
1237 C.R.V.

3.    Indicator-set with Bruan’scher tube, probably search-equipment (see picture 12, 13, 14, 15 and 16)
4.    BC-433-C, Ser. No. 14506
5.    BC-966-A, Ser. No. 45327
6.    BC-454-A, Ser. No. 140
7.    BC-455-B, Ser. No. 20162
8.    BC-445-B, Ser. No. 52370
9.    BC-929-A

Though this plane was equipped with different kinds of new radio equipment, all radio equipment had been taken out by the radio office of the Air-base Rosieres. The radio equipment had to be obtained from that office, and for the purpose of the removal of the plugs and cables had to be installed again into the plane. Also, several agent receivers of the type “Miniature Communications Receiver (M.C.R. 1)” were found.

Enclosed in this report 18 photographs.

Photo explanation.

Picture 1 and 2:     Antenna on both sides of the front of the fuselage.
3:     Equipment with Bruan’scher tube. In the right upper corner of the picture the cable installation of the antenna (shown in picture 1 and 2) can be seen.

Comments: Here are several views of the APN-1 radar altimeter. The case has been damaged and the front cable sockets removed, but the interior of the unit – chassis and attached components – is completely intact.

A video description of the APN-1, created by the infoagemuseum (Wall, New Jersey – in Monmouth County) and narrated by Mr. Ray Chase, describes the operation of the unit. A beautiful set of illustrations of a (quite intact!) APN-1 is available at the website of Aces, Contrails and Unsung Heroes, while the schematic diagram of the APN-1 can be found at this link to the Waverley Amateur Radio Society.

Pictures 17 and 18: Shows the Miniature-Communications-Receiver.

Comments for Photos 17 and 18: One aspect of the crew’s intended mission is evidenced by the subject of these images: A Miniature Communications Receiver – 1 (“M.C.R.-1”). The M.C.R.-1, a portable, tube-based miniature receiver unit, was designed for use by S.O.E. (Special Operations Executive) Agents, Special Forces, and Resistance Groups.

An M.C.R.-1 unit with its associated components is seen lying on a table. Three power packs (one of which is connected to the unit by a short cable) are present, while on the right are three “Frequency Plug-In” coil packs, each of a different frequency range (2.5 MHz – 4.5 MHz, 4.5 MHz – 8 MHz, and 8 MHz – 15 MHz), which extend the receiver’s length.

A thorough description of the M.C.R.-1 (with very nice color photographs) is available at the CryptoMuseum website. The operating manual for the receiver – in which it’s dubbed a “Midget Communications Receiver” – can be found here, while the schematic diagram of the unit (via the Waverley Amateur Radio Society) can be found here.

The Luftgaukommando Report includes a small and fascinating bonus: It contains a very actual – quite original – very genuine – surviving remnant of the McDonald crew’s last mission: a placard of operating instructions for an M.C.R.-1.

A superb set of images of an M.C.R.-1 and its associated components (including interior views of both the receiver and its power supply) as well as instructions covering its installation and use, is available at Jan Poortman’s PA3ESY Vintage Radio Collection website.

Captive Technology: German Photographs of Electronic Equipment in a Downed Special Operations Squadron B-24 Liberator – II

This – and the next – page present the 19 pictures in Luftgaukommando Report 1054, for B-24D 42-63792. The format is identical to that followed in the blog post covering the Luftgaukommando Report for B-24H Liberator Tell Me More:

By scrolling “down” the post from top to bottom, you’ll see images of the two pages in the Report listing the captions of the photos.

This is followed by a verbatim transcription of the block of the German text in those two pages. The German text is followed by its English-language translation (in italics) which I transcribed from the MACR.

Then, moving “down” through all the pictures…

Each photo has its caption – in both German and English – below it. The English-language translations are presented in italics.

The images and their captions aren’t presented in the same numerical order as in the KU Report. They’re arranged as if you were moving along the plane (or, er, uh…in this case, what’s left of the plane…) from front to rear. I’ve also added comments below some captions.

These three un-numbered images show the scope and scene of the plane’s crash. Most of the airframe and wings have been destroyed (the tail and left wing broke off during the crash) but ironically, several components of the plane’s special electronic equipment, situated in the central fuselage and nose, survived relatively or completely intact. These have been extracted from the fuselage and placed in front of the wreckage.
