B-17 Artifacts
I am a collector
of items pertaining to the B-17 and the US Army Air Forces. From the
early designs, to the B-17G's, and the later variants.
In my collection,
I have original manuals, Aviation Sextants, Radio Equipment, Gun Sights,
Cameras, Aviation Artwork, head phones, throat mics, ammo, pins, and much
more. I am looking for Gun sights, Inert Bombs, and ANY equipment
originally used on the Flying Fortress.
I flew in a B-17
on the 20th of  July.
The Confederate air force was touring in their 1944 B-17 the "Sentimental
Journey " Arizona Wing-

At Lost Nation
Airport, here in Mentor, So being the B-17 buff that I am , I took the
Monday off, and watched them fly in, they brought in a Heinkel He-111, a
Junkers Ju-88, and the B-17G. The next day I took my wife Nancy and my
son Jake to see them, and while we were their I talked to the pilot, and
for a fee, I went up for a 40 minute flight. IT WAS INCREDIBLE!!! I
got the front most seat, the bombardier seat during take-off, that's the
one at the very front of the aircraft, the plastic bubble, WOW!, it was
incredible to see the engines start up, taxi, then hurtle down the
runway at 120 mph with nothing but a 1/4 inch bubble of plastic in front
of you. After about 10 minutes, I crawled/walked around the aircraft,
absolutely awesome. Its hard to describe the feeling, with the sounds,
vibrations, smells, and sights.

In September of 1941, a new Fortress appeared with an
extensively modified empennage. Gone was the pert fin and rudder riding
precariously behind the stabilizer. Instead, a broad yet graceful dorsal fin
rose from amidships and enveloped a deadly stinger of twin .50-cal. machine
guns. A remote controlled belly turret held two more .50s. This was the
B-17E, of which 112 were built. Four hundred more followed but with a manned
Sperry ball turret replacing the remote system. The B-17E was lengthened to
73 feet 10 inches to accommodate the new defensive tail position. Top speed
was 317 mph, cruising at over 200 mph with 4,000 pounds of bombs.
The Pearl Harbor attack of December 7,1941 finally
brought the United States into the war and production of the B-17 rapidly
increased. By July 1942 the US began forming the Eighth Air Force in
Britain, equipped with B-17Es. The 'E' represented an important improvement
over the earlier B-17s, in that it had a tail turret, so eliminating a
previous defensive blind spot. On August 17,1942 United States B-17s carried
out a bombing raid on the railway yards at Rouen in France. The real
offensive, however, started on January 27,1943, when B-17s of the USAAF made
their first attack on Germany. Initially, casualties were very high because
they attacked during daylight hours to achieve greater accuracy and because
proper formation flying (to enable a group of airplanes to defend each other
with crossfire) had not yet been formulated. Delivery of the B-17G (the
major production version) helped. The 'G' was the first variant to have a
gun turret under the nose, so increasing the armament to 13 guns.
Production of the similar B-17F was undertaken by
Douglas and Vega, a subsidiary of the Lockheed Aircraft Corp., was taking
its toll in speed. The B-17F, though now armed with eleven .50-cal. guns,
could only reach 299 mph, but landing speed was up to 90 mph! Service
ceiling was 37,500 feet and range 2,880 miles. It took twenty-five and a
half minutes to climb to 20,000 feet. Three thousand, four hundred B-17Fs
were produced by the three companies.
By September 1943, the Flying Fortress showed its
final shape. During firepower tests on the XB-40, a modified B-17F, the
advantage of a chin turret was clearly proven and a new series, labeled
B-17G, sported this nasal appendage. The Bendix turret held two .50-cal.
guns and this model had a total of twelve of these weapons with 6,380 rounds
of ammunition. In all, there were 8,680 B-17Gs built by Boeing, Vega, and
Douglas to make this the largest production variation. Following the first
Model 299, the Air Corps purchased 12,725 B-17 type aircraft.

A Luftwaffe Test Pilot's Account of a Captured B-17
Luftwaffe Test Pilot by Hans Werner Lerche

Perhaps there were other aircraft that were even more
pleasant to fly than the B-17, because it did have its drawbacks: for example,
the forces acting on the ailerons were relatively high, and the rudder felt as
if it were set in concrete. But it was much more important that the aircraft was
easy to fly and land. When one had become accustomed to the higher all-up weight
and the strange instruments, it could be compared with our He 111 in the
degree of effort needed to fly it.
What was really outstanding about the B-17 which made it, together with the B-24
Liberator the standard day heavy bomber in the European theater of war? It
certainly was not fast in low altitudes; only the exhaust-driven turbo
superchargers gave the B-17 its good performance at higher altitudes. All in
all, that was for me the most admirable thing about American planning, namely
the consequential pursuit of a concept once it had been recognized as correct,
in this case the effectiveness of raids carried out by well-armed high-altitude
bombers flying in close formations.
One must remember that several years would pass between planning and execution
of a concept. Possibly only the idea of keeping the attacking fighters at bay
with heavily armed bombers flying in close formation and firing from all
'portholes' had to be revised. This consequently happened after the raid on
Schweinfurt which, due to the long distance involved, had to be carried out
without fighter escort, During this raid the USAAF bombers suffered heavy losses
from twin-engined Zerstorer and single-seat fighters attacking with rocket
missiles, which naturally caused quite a crisis. The correct solution to this
problem was soon found: elimination of the sluggish, rocket-carrying Luftwaffe
'destroyers' by escort fighters -- and several versions of these, with excellent
performance, were also soon available. Nor did the rather poorly adjusted
control forces on the American bombers have much detrimental effect, as this was
certainly not decisive during the approach at great height, and even less so
after the bombers had been equipped with an excellent three-dimensional
autopilot. It must be stressed that the respectable speed of the B-17 at higher
altitudes was due solely to its excellent exhaust-driven turbo-superchargers.
But for the production of these devices one required not only the know-how but
also large quantities of heat-resisting materials which we were lacking in
Germany.
Occasionally I would receive via Switzerland foreign reports on German aircraft,
and it was interesting to read that they quite often not only praised the
construction of the machines but the engines as well, more often than not
concluding that the Germans just did not have the necessary heat-resistant
metals for even better performance.
