Aviation 101 Boeing B-17                              


     In Aug. 1934 the US Army Air Corp. submitted a request for proposals from the aircraft industry for a multi-engine bomber to replace the Martin B-10. Three companies responded; Douglas with its DB-1, Martin and the Model 146 and Boeing with the Model 299. During the competition held in Sept.-Oct. 1935, the four engine Boeing entry was considered to be superior to the other two twin engine candidates. In spite of a price tag almost double that of the two smaller aircraft, and in spite of the crash of the Boeing prototype on 30 Oct, it was Boeing Aircraft Co. that eventually received small orders for the Y1B-17, and in July 1940 an order for 512 of the B-17s was placed by the USAAC.                                    

     After the Japanese attack on Pearl Harbor on 7 Dec 1941, production of the B-17 quickly accelerated, and by the time production ended in May 1945 a total of 12,731 of the "Flying Fortresses" had been built by Boeing, Douglas and Vega (a subsidiary of Lockheed).                                                                    

     At the conclusion of the war, thousands of aircraft were ferried back to the USA and most were sold as scrap and melted down. Some were used by the USAF in secondary roles, with most of those being phased out by 1959. Some were sold or donated to many countries around the world, including many to South America and 25 to Bolivia. Twelve of these were operated by Lloyd Aereo Boliviano; the last B-17 was sold to a private freight company in 1971.  

     As of Aug. 2013, 46 intact B-17s were known to exist; on static display, being restored or air-worthy. And by 2015 only ten aircraft are now considered air-worthy.                                                          

     One of those survivors still flying is the "Sentimental Journey", operated by the Commemorative Air Force and based in Mesa, AZ. An extensive photographic tour of this special aircraft can be seen by clicking "A Classic B-17G..." on the top left side of this page.

Hollywood career: In 1946 this aircraft was purchased by Paul Mantz from the War Assets Corp. in a lot of 475 wartime surplus bombers and fighters that he bought for $55,000. Of this large "fleet" of aircraft, which included 78 other B-17s, he chose twelve to use in movie making; the rest he sold for scrap at a large profit. Forty-two year old Mantz, an air racing pilot, was also a movie stunt pilot and he could see opportunities in these almost new, but surplus aircraft. Later that year he formed Paul Mantz Air Services which provided planes and pilots to production companies for the filming of movies. This particular B-17F (c/n 8296) was used in several motion pictures including: 'The Best Years of Our Lives"  - 1946; "Command Decision" - 1948; "Chain Lightning" - 1950; among others.

1944. It was registered as 41-24434 by the USAAF and was destined to fulfill its roll in the war effort as a long-range heavy bomber. It might have seen some brief action in July of 1942 when it was based in England, but fate had laid out a different path for this B-17F.


It was going to be assigned to the 15th Photographic Reconnaissance Squadron of the 3rd Photo. Recon. Group stationed at RAF Membury, England. Prior to beginning this new career, "The Mud Hen" as it would be called, briefly returned to the US. I assume this would have been for installation of new electronics and photographic gear. The mission of the 15th PRS was to provide photographic intelligence and surveillance of enemy forces in southern Europe during the Allied campaign.


After leaving England by Dec 1942, the 15th PRC operated out of Algeria, then Tunisia in northern Africa. After a short return to the US in July 1943, likely for equipment upgrades, aircraft 41-24434 was stationed in Italy, probably for the remainder of the war.


In 1945, following the war, this aircraft was registered as N60475 and went to work at Sperry Gyroscope in New York. This company continued work on a wide variety of aircraft systems and electronics including analog-computer controlled gun sights, airborne radar systems and automated takeoff and landing systems. Sperry also invented the ball turret gun used in the B-17 bomber. This involvement with Sperry continued until 1950 or 1951, when the aircraft was sold to the brokerage firm Charles Babb and Co. dealing in new and used aircraft and aircraft parts. From there N60475 found it's way to Bolivia and became CB-79.




Accident: On 29 Dec 1958 this aircraft was involved in an accident near Uncia and was written off as damaged beyond repair.

The story of how it got to Bolivia: This aircraft was flown to Russell Field, TX from the WAA storage yards in Altus OK.  It was used as an airport marker for several years with the airport name painted prominently on it's wings. It eventually was one of the surplus B-17s bought up by Owen W. Williams, possibly a bit illegally, and was assigned the tail number N66570. Williams evidently had trouble registering the aircraft as it turns out the seller didn't actually own it and, as with several other Williams' B-17s it was quickly sold out of the country to a Bolivian company. -  Information taken from the Aero Vintage Books website.

The Accident: On 5 Sept 1955, LAB CP-597, on a cargo flight, collided in mid-air near Cochabamba with another LAB aircraft, the DC-3 CP-572, which was on a scheduled passenger flight. The B-17 crashed near Cochabamba taking the lives of the three occupants. The DC-3 was substantially damaged in the collision, but was able to make an emergency landing at the Trinidad airport; no injuries were sustained by the passengers or crew. The DC-3 was repaired and returned to service.

This registration number refers to a B-17F-65-DL  aircraft with an interesting history,but which does not have any connection to Bolivia or Lloyd Aereo Boliviano. Some confusion comes from the fact that some photographs of this plane show a paint scheme with the letters LAB; this refers to the Nicaraguan company Linea Aerea Borinquen, that registered the aircraft as AN-AMI in 1960 shortly before they went out of business. Another source of confusion comes from a registration of CP-633 or sometimes listed as P-633. Neither of these is correct; the company requesting the new registration is listed as Empresa Eximas Ltda. - of Bogota, Colombia.
