In this brief, I have put together some of the B-17 photos which I have purchased over the past three months to participate in and contribute to a B-17 ceremony in France in June 2013.

Getting a Sense of What it Was Like
2. Viewing the B-17
• As part of my preparation for participating in
the June 2013 event honoring the B-17 in
Noirmoutier, France, I sought some original
photos or good copies from original negatives
to shape a portfolio of images to understand
what the plane and the experience was like
• What follows are some of those originals or
copies made from the original negatives
23. Variants and Factories
• With Boeing, Vega, and Douglas all building B-17s in different locations
(Boeing was in Seattle, WA while Douglas and Vega were both in Southern
California) it was impossible not to have differences in aircraft built on
different production lines at different times and in different locations.
• It was thus decided to come up with a system to determine what model of
B-17 the aircraft was along with when it was built and where it was built.
Block numbers would begin with the model of the aircraft such as B-17F.
Next would be the Block number itself and would be started with the
number one. For example: B-17F-1 would be the first block of B-17Fs.
• These numbers would be increased by five per block so that the second
block of B-17Fs would be numbered B-17F-5. The reason for this is so that
if changes were made at the field modification centers that the planes
were shipped too following production that these modifications could be
tracked as well using the block number.

• Lastly, the plant ID was incorporated into the block number
as well. BO was Boeing in Seattle, DL was the Douglas plant
in Long Beach, CA, and VE was the Vega plant in
Burbank, CA. With the B-17F, there were 27 line blocks
from Boeing, 17 from Douglas, and 11 from Vega.
• So, B-17F-80-BO was the 12th block from Boeing, B-17F-25-
DL was the 6th block from Douglas and B-17F-30-DL was
the 7th block from Vega.
• Other improvements to the B-17F were made to the
landing gear, brakes, oxygen system, bomb racks, ball
turret, bombsight/autopilot link, astro-compos, and a nose
bubble in the upper nose section.
