| The story about the encounter between a YB-40 and a captured P-38 is bogus. To quote this web site http://www.defensemedianetwork.com/stories/my-brilliant-mistake-the-yb-40/ :
"After World War II, several versions of a remarkable story were recounted by Martin Caidin and reiterated by Glenn Infield and other authors in the menís adventure magazines: 1st Lt. Harold Fischer, a bomber pilot in the Fifteenth Air Force in Italy, was said to have borrowed a YB-40 from the Eighth Air Force. Fischerís purpose was to entrap Italian fighter pilot Lt. Guido Rossi, who was using a captured American P-38 Lightning fighter wearing U.S. markings to shoot down stragglers on the way home from missions, initially posing as a friendly escort. Fischer lured Rossi Ė who knew plenty about the B-17F but nothing about the more heavily-armed YB-40 Ė and shot him down. Both pilots survived the war and later met, according to the tale, but Fischer was killed in the 1948 Berlin airlift. In one version of the story, Rossi subsequently romances Fischerís widow. But no YB-40 ever appeared in Italy and no one named Fischer is listed among Berlin Airlift casualties. Apart from the fact that an Italian pilot with a different name, Lt. Angelo Tondi, flew a captured P-38 and may have used it to deceive U.S. bomber crews, the YB-40-in-Italy story appears to be more fantasy than fact."
Martin Caidin had a reputation for mixing fact and fiction, and this is one of his bigger whoppers.

| The YB-40 was a derivation of the Boeing B-17, in which additional guns were added in hopes that these heavily-armed B-17s would be able to "escort" the other bombers, protecting them from enemy fighter attacks when beyond the range of friendly fighter escort. Lockheed-Vega had the task of doing the conversion work on the Boeing B-17s, but only twenty YB-40s were made, as well as four training models known as the TB-40. Changes included a remotely-controlled chin turret (which later became standard on the B-17G model), twin .50 caliber guns in the waist positions (instead of the single guns), an extra twin gun power turret behind what used to be the radio operator's gun position, and sometimes extra cheek guns in the nose. The bombs and bombardier were left behind, and extra ammo for the guns was carried. Even with the reduction in weight without the bombs, the added weight of guns and ammo made the aircraft heavier and slower. As a result, once the other bombers had released their bombloads, the YB-40s were outpaced by their lighter brethren, and so failed in their role as escorts. The program was made obsolete not only by its own failures, but by the appearance of long-range fighter escorts that could fill the role much more ably.

| I have done research on the YB-40s of the 92nd BG and am freinds with a pilot of one of the YB40s, George Ott. He flew the plane called "Dakota Demon". There is a story about George and this plane at www.scottnelsonart.com
See the story "Dakota Demon-Brush With Royalty".
The story about a YB-40 shooting down an enemy piloted P-38 in Italy is not true.

| There is a great chapter about the use of YB-40s as decoy ducks once they were found inadequate for their original mission in the book Flying Forts by Martin Caidin. |

| The dozen or so testbed aircraft were converted Vega-built B-17F's (some converted by Douglas Aircraft) with varying mixtures of armament. Some had dual dorsal turrets, and a few with 40mm cannon, presumably installed in the tail gunner's station. All had their bomb bay's converted into .50-cal ammo storage and were protected in places by armor plating. These two additions, combined with the increased drag of the extra guns and turrets, added to the overall weight of the YB-40 and they had trouble keeping up with the formations of "regular" B-17's after they had released their bomb loads. The test program was discontinued after a few weeks and the aircraft either returned to their orginal B-17F state or returned to the States for use in training. One YB-40 was indeed lost in action. One final note to add: while the overall project was seen as unsuccessful, the chin turret that orginally appeared on the YB-40 was incorporated into the B-17G models, and provided defense against the head-on attacks the Luftwaffe used to attack them. |

| The YB-40 was used in Italy to shoot down a P-38. The P-38 had been captured by the Italians and was used to shoot down straggling bombers on their return to base. The YB-40 was able to lure the P-38 in and shoot it down. It makes for an interesting career for the YB-40. |

| The YB-40 was first used operationally on 29th May by the 92nd Heavy Bomb Group whilst stationed at RAF Alconbury. The aircraft were not particularly successful and were taken off operations in August. |

| I'm given to understand that the YB-40 first saw combat during a bombing mission to the sub pens at St. Nazaire, France on May 29, 1943. If anyone has any additional information about that mission, it'd be appreciated. I'm particularly interested in info. on the 94th Bomb Group and their participation in this raid.

| A number of years ago I read an article about this version of the B-17. It was heavily armed. Used as a bomber escort, this aircraft proved to be a little too slow. As the insrciption says on the bottom of the photo, this plane could not be shot down! |
