Boeing B-17 Flying Fortress

Frustrated in their efforts to acquire a fleet of strategic bombers for service with the Army Air Corps, US Army planners - who were devotees of the theories expounded by Brig Gen William 'Billy' Mitchell - inserted the thin end of an important wedge when they ordered a small number of YB-17 prototypes in January 1936, ostensibly for the nation's defence. Originating as the Boeing Model 299, the prototype was built as a private venture, Boeing gambling heavily on producing a winner that would bring a large military contract. It must have seemed to Boeing that their gamble had failed when, almost at the end of the military trials, the Model 299 crashed on take-off. Fortunately investigation proved that the aircraft had been flown off with the flying controls locked and safety of the basic design was not suspect.

It was not until 1938 that the USAAC was able to place an order for 39 production B-17B, the last of this batch entering service in March 1940. These were the first B-17 production aircraft to be equipped with turbocharged engines, providing a higher maximum speed and much increased service ceiling. Of the B-17C which followed, a batch of 20 were supplied to the RAF (designated Fortress I) and used operationally in Europe for evaluation, leading to improved B-17D and B-17E aircraft with self-sealing fuel tanks and revised armour and armament.

The B-17E was truly a flying fortress, armed with one 7.62mm and 12 12.7mm machine-guns for defence and able to carry a maximum 7,983kg of bombs. Most extensively built variant was the B-17G (8,680), being built by Douglas and Lockheed Vega as well as at the Boeing plant, Seattle. Pratt & Whitney R-1820-97 radial engines and improved turbochargers enabled the B-17G to operate at an altitude of up to 10,670m; and the addition of a chin turret below the nose (containing two 12.7mm machine-guns) provided better defence against the head-on attacks being launched by Luftwaffe fighter pilots in their attempts to reduce the numbers of Fortresses striking daily at strategic targets deep in German territory.

Special variants included the B-40 with up to 30 machine-guns/cannons, which was intended as a B-17 escort, but proved to be an operational failure; BQ-7 pilotless aircraft packed with explosives to be deployed against German targets by radio control, which failed due to unreliable control equipment; CB-17 and C-108 transports; and F-9 long-range B-17 equipped to serve as an air-sea rescue aircraft and able to deploy a lifeboat carried beneath the fuselage.

In Britain, more than anywhere else in the world, the B-17 evokes vivid memories of courageous aircrew who day after day - despite sometimes horrific losses - continued to attack targets in Europe until victory was won. For Boeing, their private-venture gamble paid off: a total of 12,731 Fortresses were built by the Boeing, Douglas and Lockheed team.

To all,
I would like to fly the Swamp Fire around the world. I have Google Analytics recording all the hits from all the different countries. I ask you to visit the site and send the address to your friends and then have then do the same Etc, Etc, Etc. I think it would be interesting to see the results and see how fast and how far this will go.

As a radio operator on a B-17G, we dubbed Pacific Tramp 2, it was the biggest plane in the air at the time. I never thought they would ever get any bigger. Obviously I wasn't able to foresee the future but not too long after we landed in the Pacific along came the B29. Our beautiful 17 was outsized. However, she was our baby & I painted gorgeous Esquire girls on the nose to prove it. Our crew headed up by James Gordon Pugh of California was an 18 year old pilot entrusted with a million dollar plane & 9 human lives, some of whom were older than he was but none with his abilities which were outstanding. I have many times tried to find him to no avail. In our converted 17 we were fitted for our job as an air/sea rescue team with an 0wens unsinkable twin engine boat capable of carrying 15 people with enough food & supplies for 15 days, able to convert sea water to drinkable, SOS radio,inflatable cover and many other features. It was a remarkable plane & crew. I often think of them.

My dad flew 33 successful missions in one during WW11 and got shot down twice i beleive it was a b17 i am not sure

Roy Bittner, maureen51(@)msn.com, 26.02.2010

In 1950 I was at Kindley AFB Burmuda Flidht D 1st Rescue Sqd. We had 3 of the B-17 with the drop Boats under the bellies. They had no trouble getting off the ground or landing with them. They did a lot of escourt duty for planes with minor trouble comeing home from europe.

My father, Melvin Brush, served with the 305th BG out of Chelveston, England. While he was alive he participated in the reunions that they BG group had. I was lucky enough to go with him to one of them help in Seattle Washington. Mel passed away almost 6 1/2 years ago and would love to get ahold of any of his old commrades who remember him and served at Chelveston during the war.

For its time in history, this was the best plane ever.I was the radio operator gunner for 31 missions in a B17 and it kept on flying despite many savage hits by fighters and flak. My last 15 missions were on B17 42-102547 (Rose of York)which was christened by the present Queen of England on July 6, 1944

Carol Rose Offutt, rose8220(@)hotmail.com, 27.01.2010

My father flew 54 missions as pilot of the B-17 in Europe with the 92nd BG. His story is For This Marvelous Country.

great plane for photo work. stood up good under crash conditions to....

Bill Varnedoe, billvar(@)comcast.net, 03.01.2010

I was navigator on the Crow crew, 550SQ, 385BG.
I am the Historian of the 385th Bomb Group Association.
That 13th gun in the radio hatch was removed, as it did not do any good (other than making movies of gunners in combat.) Besides, the radio operator manned a waist gun over enemy territory after the crew was reduced to 9 men!!

Bombs away ! dudes, relax man!

Edward P Gilmore, egilm4817(@)aol.com, 26.04.2009

I was on a crew of an air sea rescue B17 in 1945 stationed in Abadan Iran. The plane still had the ball turret behind the boat. Can you tell me where I can get a model of this plane?

Gary McFall, tgmcfall2(@)yahoo.com, 23.12.2008

Tom, les_indestructibles(@)one.lt, 03.11.2008

Hello, can someone tell me what plane was used as a primary bomber in USA before the Boeing 17 production?

Joe Hodder, Joe Hodder85(@)aol.com, 03.08.2008

I don't knw how the air-sea rescue version was designated but the F-9 was a Photo variant of the G Model. It had a tri-cam array in place of the chin turret, the standard vertical camera station in the radio room and a sling to aid the photographer taking long focal length pictures out the waisst windows. The aircraft didn't hae any guns, armor plate, or bomb racks. Some had "Tokyo Tanks" in the bomb bay which gave them a 14 1/2 hour range with a 45 min. reserve. One such aircraft was assigned postwar at Neubiburg to eveluate several items of German aerial photo equipment.

I was a tailgunner in Glatton, England during the War and can't remember for sure what the takeoff speeed was with a loaded airplane; can anyone help?

stephen russell, stephenrusell(@)sbcglobal.net, 15.06.2008

Love the B40 gunship mode & the B38 superfast models.
2 bad B40 didnt work out in the skies.
Seen No models etc on B-40 or B-38 variants.

Chuck Neilson, chuckelmon(@)thunderbird.com, 01.06.2008

I flew 35 missions out of Foggia,Italy as a tail gunner during 1944-45 and never saw a more airworthy plane. We came back over the Adriatic, fearing ditching in the water, but made it in on one engine full power, one half power & two dead engines. My hat was off to that plane.

'Ol Glenn, chilicook(@)hotmail.com, 21.04.2008

I grew up in a small town in Nebraska near an airbase where air crewa learned formation flying to maximize the effectiveness of their firepower against German fighters. What a majestic plane the B-17 was.

EM Carlaw, emctlc(@)juno.com, 13.09.2007

Hello, I have a question concerning the data plates on the -97 series of engines during WW2. I have heard that early in the war the acceptance dates were cut from the data plates to keep the Germans from finding vital information. Could someone update me on this info? Thanks

GIULIANO, giuliano(@)lartsrl.com, 09.07.2007

CIAO I AM LOOCKING FOR THE MANUAL OF CREW OR ROFI(RADIO OPERATOR FILE IN.

I was a small boy in 1941, only 6&1/2 years old when my father died of kidney trouble and I moved from Hayden, AZ to Tucson, AZ with my mother. We lived about three miles from Davis Monthan Air Force Base and watched the B-17 Fortresses fly almost continuously. They were awesome and gave me a thrill each time they came over the house. I finally got to climb into one at Peachtree-DeKalb airport here in DeKalb County about a year ago. I was surprised at the cramped conditions in which those aviators had to work. I am six feet and 240 and would never have made it into the cockpit. I flew S2F Trackers in the Navy and had the same Wright 1830-82A engines with sealed harness for sea duty. What a great engine to fly. Call me 404-325-4866 Cell in GA.

Do you have any comments about this aircraft ?
