- Bruce Guthrie Photos Home Page: [Click here] to go to Bruce Guthrie Photos home page.
- Recognize anyone? If you recognize specific folks (or other stuff) and I haven't labeled them, please identify them for the world. Click the little pencil icon underneath the file name (just above the picture). Spammers need not apply.
- Copyrights: All pictures were taken by amateur photographer Bruce Guthrie (me!) who retains copyright on them. Free for non-commercial use with attribution. See the [Creative Commons] definition of what this means. "Photos (c) Bruce Guthrie" is fine for attribution. (Commercial use folks including AI scrapers can of course contact me.) Feel free to use in publications and pages with attribution but you don't have permission to sell the photos themselves. A free copy of any printed publication using any photographs is requested. Descriptive text, if any, is from a mixture of sources, quite frequently from signs at the location or from official web sites; copyrights, if any, are retained by their original owners.
- Spiders: The system has identified your IP as being a spider. I love well-behaved spiders! They are, in fact, how most people find my site. Unfortunately, my network has a limited bandwidth and pictures take up bandwidth. Spiders ask for lots and lots of pages and chew up lots and lots of bandwidth which slows things down considerably for regular folk. To counter this, you'll see all the text on the page but the images are being suppressed. Also, a number of options like merges are being blocked for you.
Note: Permission is NOT granted for spiders, robots, etc to use the site for AI-generation purposes. I'm excited for your ability to make revenue from my work but there's nothing in that for my human users or for me.
If you are in fact human, please email me at email@example.com and I can check if your designation was made in error. Given your number of hits, that's unlikely but what the hell.

- Specific picture descriptions: Photos above with "i" icons next to the bracketed sequence numbers (e.g. " ") are described as follows:
- AIRXC_210518_05.JPG: Project Egress
Built for the Smithsonian National Air and Space Museum on July 18th, 2019
- AIRXC_210518_11.JPG: A Unified Hatch
In 1967, during a routine countdown simulation on the Apollo 1 spacecraft, an electrical fire erupted inside the command module cabin.
Under ideal conditions, the three-part hatch could be opened inwards within 60 to 90 seconds, but the fire spread quickly within the pure oxygen environment, and the atmospheric pressure difference was too great.
The astronauts were unable to exit in time.
Following the Apollo 1 tragedy, engineers were tasked with designing a new hatch that could be opened in 3 seconds, and allow the crew to egress in under half a minute.
The new hatch design integrated the three layers into one, and equipped the perimeter of the door with fifteen latches, actuated by five strokes of a ratcheting handle. It also included a plunger mechanism, a gas powered piston to push the hatch open and attenuate travel, a manually operated pressure dump valve, and a screw jack attachment for emergency closure.
This impressive feat of engineering was unprecedented. It is estimated around 150 new tools were designed and built just to work on it.
One account refers to the unified hatch as "the most carefully engineered and manufactured door ever built."
- AIRXC_210518_22.JPG: Artist Jen Schachter recruited a team of over forty makers and fabricators from around the country to contribute to Project Egress.
Referencing the 3D files and dimensioned drawings, each artist precisely manufactured one piece of the hatch assembly using a process of their own choosing.
The resulting sculpture is a patchwork of materials and techniques showing the hand of each builder and the ways we interpret aerospace history and material culture.
Project Egress is a celebration of not only the technology itself, but the thinkers and makers, seen and unseen, who made the first lunar landing possible.
The Project Egress hatch was assembled by Adam Savage, Andrew Barth, and Jen Schachter at the National Air and Space Museum before a live audience, on July 18th, 2019.

- Bigger photos? To save server space, the full-sized versions of these images have either not been loaded to the server or have been removed from the server. (Only some pages are loaded with full-sized images and those usually get removed after three months.)
I still have them though. If you want me to email them to you, please send an email to firstname.lastname@example.org
and I can email them to you, or, depending on the number of images, just repost the page again will the full-sized images.
- Connection Not Secure messages? Those warnings you get from your browser about this site not having secure connections worry some people. This means this site does not have SSL installed (the link is http:, not https:). That's bad if you're entering credit card numbers, passwords, or other personal information. But this site doesn't collect any personal information so SSL is not necessary. Life's good!
