Butterfly Valve Control, Titan II Missile

12 December 2009. At the Titan Missile Museum / Site 571-7, Sahuarita, AZ.

 

See www.crypto.com/blog/titans/

 

Before the missile could be launched, a six character alphabetic code (kept in the EWO safe) had to be entered to unlock the missile fuel line. After seven incorrect tries, the valve would lock shut permanently.

 

The list of test codes taped on the side of the rack is legible at full resolution:

1. CJJPDM

2. NVALJU

3. ENVLAN

4. ECUPAX

5. NVJLPP

6. DSNRDR

7. AAAAAA

8. LLLLLL

9. ZZZZZZ

 

Nikkor 50mm/1.4 AF-S lens (@ f/2.8), Nikon D3s camera (@ ISO 800); available light, handheld.

 

No emulsions were harmed in the making of this image.
