I grew up in Canoga Park and West Hills.... I got to see the Santa Susanna mountains light up when they ran tests when I was a kid in the '60s... then I got lucky:
I worked at Rocketdyne during the 80s... programming 3 and 4 axis Coordinate Measuring Machines, writing data evaluation and utility programs, and Inspection procedures in the "Precision Measuring Room" for the SSME QA organization... there were only about six of us that did that as the technical staff that over saw about 40 Machine Parts Inspectors [A 3 shift operation during the height of SSME]... We touched the hardware for everyone of the shuttle engines... As far as I was concerned workin' at "The Rocket Factory" was my ideal job...
We had a mixed batch of stuff to work with: Zeiss CMMs [applications to drive the machine and write "measuring routines" was written in HPL on 9000 series "calculators"], an Italian CMM made by DEA with a DEC pdp-11 with 16k of 12 bit core [A C64 had more computing power]... [the measuring app was loaded via paper tape and output was either via DECWriter and/or punch tape]. I got to write an app to read data punch tapes on a Model 43 Teletype Paper tape reader and convert them to an ASCII txt file on a IBM-PC XT
In the mid 80's they upgraded the DEA to use an HP computer that ran HP Rocky Mountain Basic... we did not have anything networked-- it was all sneaker net so I had to write an app for that HP to do a matrix coordinate rotation [from raw coordinate system to measured coordinate system] on the recorded measurements and then output them as a text file to a 5 1/4 inch floppy disk. The disk was walked over to the IBM PC-XT which then read the HP sector formatted disk using a commercial app and written to the IBM's "massive" 10 Mb disk. We then either plotted the data or wrote it to a floppy and delivered it to the Stress engineers... As I understand it that app lasted 9 years without a revision [long after I left]. I also wrote a plotter app that drove an 8 pen HP IEEE-488 Bus Plotter
Languages? MS / IBM compiled basic, HPL, early on we had a time-share plotter app written for us in Fortran, Turbo Pascal [which is what I used to write most of the utility apps for PC because it was cheap and fast]. We also delved into HP calculator programs [HP11 and HP-67].
I once got to go up to the Hill for a static firing of a set of Atlas engines [three engine set] at 3/4 of a mile away the engines sonic waves prevented me from catching a breath while the engines were firing...an F-1 has about 10 mtimes the thrust as an Atlas Set.
Oh the stories...The memories...
