A First Person ‘Insider” View of the Birth of America’s Apollo Space Program

My Apollo Space Program memories are an exciting 11 year short story of life changing events, experiences and professional endeavors. A few such memories are listed:
04 Nov 1957 (plus a day or two) – As a senior engineering student I stood on the roof of the Sigma-Chi Fraternity House at Georgia Tech and watched the pin-point “moon light” of Sputnik pass over Atlanta GA. A few weeks later, I read a TIME article about Werner von Braun and the Peenemunde Rocket Center in Germany. I still remember the magazine photo of von Braun (with his arm in a cast) surrendering to the allies!
16 June 1958 - Started my aerospace structures career as a Chrysler Contractor with the Army Ballistics Missile Agency (ABMA) at a desk located on a third floor stairwell landing of ABMA Bldg 4488, ironically just 4 or 5 hallway doors up from von Braun’s office! As I remember, we only exchanged a smile or a nod as we met in the hallway! A few times I shared a cafeteria table with Dr. Hermann Obreth, von Braun’s college physics professor from Germany. He did not have the security clearances required to go to the Staff dining room with von Braun and the Army Brass!
4 May 1960, I witnessed from a hill (~300 yards away), the first static firing of the eight engine SATURN booster at MSFC. My chest was hit by the blast before my ears heard.
June 1960 thru 1963 – As a Brown Engineering Contractor in the NASA Structural Analysis Group in MSFC Bldg 4610, I was responsible for the design development [1] of the SATURN Booster Internal Structure Load Analysis [2]. Based on my engineering calculations [3], the first launch of the SATURN vehicle was pushed back for about a month to resolve structural load concerns! The first SATURN I vehicle lift-off from Cape Canaveral, Florida was successful at 9:06 a.m. (CST) on 27 Oct 1961.
Mid 1960’s – Late one work day during a structural test in MSFC Bldg 4712, I was standing about 10 feet from the nearest of approximately forty tension straps (~ one inch thick, ~10 inches wide and ~15 feet long) that where used to apply loads to a full-scale SATURN V intertank static test segment. I suddenly had to jump back many more feet when the straps (each fully loaded with ~50,000 lbs tension) started vibrating violently and then snapping in a loud explosive manner! While the structural test was under way at Bldg 4712, a live static firing of the SATURN V engines was started at the propulsion test facility about a half mile away causing a local ‘earthquake’ wave ripple under the test fixture in Bldg 4712! Dr. von Braun sent out a memo the next day saying all MSFC test scheduling would be coordinated to prevent such problems in the future.
Aug 1968 thru 1969 - I worked as a Boeing Contractor in the NASA/MSFC Saturn Apollo Flight Evaluation Working Group. On 16 July 1969 – I was blessed to be at the Kennedy Space Center (KSC) viewing area for the Apollo 11 launch along with a few hundred other MFSC colleges. At Liftoff (9:32 a.m. EST) we were all yelling very loud and proud GO - GO –GO (like at a football game, but much more so)!!
20 Jul 1969 – Four days later at home alone and kneeling in front of the TV – when hearing the intercom words from Buzz Aldrin - “Contact Light” - I immediately felt the chills traveling all along my spine – we had touched the Moon [4]!
Footnotes:
[1] A design development example was the presentation of the loads analysis results for the loss of one booster engine during launch at a joint meeting (1962 or 1963) between the MSFC Structural Design and Analysis groups and the Houston Space Flight Center Astronauts (Frank Borman and Deke Slayton).
[2] The structural analysis effort was highlighted in the 2 Aug 1961 issue of the MFSC Marshall-Star weekly news bulletin.
[3] A few years ago I compared my ‘primitive’ calculations to recalculated results using a modern structural finite element computer program. The technical paper is located in the software user’s conference web site at http://www.mscsoftware.com/support/library/conf/auc99/p01299.pdf.
The SATURN Loads Analysis originals (vellums) were recently given to the Space and Rocket Center Museum Archives in Huntsville, Alabama.
[4] Since those Apollo 11 years of memories, I have had opportunities to work on the Hubble Space Telescope project with Jan Davis (before she became an astronaut), on a Space Station Microgravity project with Dr Stuhlinger (von Braun’s Chief Scientist), and with other Mission Specialist Astronauts on various Space Station payload projects. I am now working with the Army Aviation Directorate (AED) at Redstone Arsenal; ironically, back at Army building 4488, around the hallway corner from my desk area in 1958!
