The a part of the Apollo missions my father labored on is proven on the prime of this picture from the Apollo 11 launch on July 16, 1969.

I used to be 13 years outdated once I realized my father had labored on NASA’s Apollo moon missions.
Maybe I might be forgiven for being initially skeptical. The second he selected to impart this data to me, we had been settling into our seats on the outdated Mission to Mars journey at Disneyland, awaiting our launch for a quick capsule journey to the Pink Planet earlier than a scripted malfunction required a hasty however protected return to Earth.
However the story my dad was about to share with me was no fantasy or fairy story, nor was it as dramatic or glamorous as those who Hollywood makes motion pictures about.
With the 50th anniversary of NASA’s first journey to the moon this week, I have been reflecting on what it meant to be a toddler of the 1960s and ’70s caught up within the pleasure of the moon missions. The launches, the more and more bold missions, had been occasions that punctuated the lifetime of a younger schoolboy who choked down Tang — a fruit-flavored powdered drink combine made common by NASA missions — with hopes of being an astronaut however unaware of the contribution his personal father had already made.
My dad spent many years working as an engineer for aerospace and protection contractors in Southern California, together with TRW, Litton Industries and Magnavox. He shared little, both because of the extremely technical nature of his work or extra seemingly due to restrictions associated to his safety clearance.
Whereas his work could have been a thriller to me, his love of area journey wasn’t. He got here of age because the area race was gearing up and had a eager curiosity within the area program. When my brothers and I had been youngsters, our dad would wake us up early on launch days so we may watch the occasion with him on TV (no DVRs then). He used the yard telescope to point out us the touchdown websites for the Apollo missions.

NASA’s bid to get people again to the moon

As with every large endeavor, it is essential to grasp there have been a whole lot of 1000’s of individuals concerned, and I do not wish to give the impression that my father was rubbing elbows with Gene Kranz or Chris Kraft on the Mission Management Heart in Houston. (Though, like most of the period, he would’ve appeared the half, full along with his close-cropped hair, horn-rimmed glasses and white short-sleeve gown shirt with a distinguished pocket protector.)
Like these different 1000’s of people that lent a hand, he made a small however important contribution that helped result in a profitable mission. Whereas most of the contributors had been largely centered on getting the astronauts to the moon and again safely, my dad’s focus was on maintaining them protected on the bottom whereas they awaited launch.
That was no straightforward job, contemplating the astronauts had been strapped inside a capsule perched on prime of a Saturn V rocket containing the greater than a half-million gallons of gasoline and 400,000 gallons of liquid oxygen essential to push the Apollo spacecraft out of the Earth’s ambiance. That was additionally sufficient to feed an explosion equal to 2 kilotons of TNT.
The escape tower
Within the occasion of a launch emergency, the job of rapidly separating the crew from the Saturn V rocket would fall to the launch escape tower, basically one other, a lot smaller rocket mounted above the capsule that may pull it from the launch automobile and deploy a parachute when it was a protected distance away.
The escape tower lifts a capsule throughout a check of the Apollo Launch Escape System in June 1965.

A collection of explosive bolts held the escape tower in place till both an emergency use throughout an aborted launch or its scheduled jettison three minutes after liftoff. Maintaining these bolts in place till both of these occasions occurred may save lives and stop injury to the launch automobile.
However the bolts’ stability was threatened by the ocean of radio wave and electromagnetic interference swirling across the rocket earlier than launch, which may inadvertently detonate the gadgets.
A staff of engineers, together with my father, was answerable for placing the bolts by way of a battery of exams to establish vulnerabilities which may come up from the varied radio frequencies getting used on the launch pad, in addition to static electrical energy originating from the electrical programs.
Whereas these exams had been being performed within the mountains exterior of Los Angeles in early 1967, the significance of the staff’s work was hammered house when the three astronauts within the Apollo 1 crew died in a swift however highly effective capsule fireplace on the opposite aspect of the nation. The fireplace that killed Roger Chaffee, Virgil “Gus” Grissom and Ed White — throughout a launch gown rehearsal for the primary manned journey across the moon — was brought on by a mixture of a cabin filled with pure oxygen, flamable supplies and susceptible wiring, in accordance with the NASA abstract.
Manned Apollo flights had been suspended for almost two years whereas this system underwent assessment and redesign. The investigation decided that the Command Module — the capsule by which the astronauts would journey into area and again — was extraordinarily hazardous but additionally discovered the check’s emergency preparedness to be insufficient.
The catastrophe led to a number of design, manufacturing and procedural modifications. It additionally highlighted the danger astronauts confronted even on the bottom, actually a priority for my father, who was so devoted to the method that he was on the distant testing web site just a few days after the fireplace, when my mom went into labor with me. A army escort ensured that my father was within the supply room in time.

Two and a half years later, all these NASA efforts paid off when, on July 20, 1969, Neil Armstrong and Buzz Aldrin stepped onto the floor of the moon. My household had taken a fast drive that day down the coast to San Diego to go to the Palomar Observatory, with hopes of seeing the spacecraft orbiting the moon by way of the Hale Telescope. Sadly, my mother and father, my older brothers and I missed the precise moon touchdown when my dad’s Jeep had two flat tires on the best way house, however we had been again in Torrance in entrance of our 21-inch black-and-white TV in time to look at Armstrong ship his well-known speech.
NASA would go on to make 5 extra moon landings between 1969 and 1972, and the escape tower by no means had for use by astronauts throughout a launch. A NASA report compiled in 1973 discovered that no failure of the pyrotechnic gadgets was detected throughout any of the Apollo missions. The reliability of the bolts was attributed, “in massive measure,” to the testing strategies, amongst different issues (PDF).
It was one of many many small parts of an infinite undertaking, and although my dad was soft-spoken and never one to brag, he was pleased with the contribution he made to the Apollo program and privately thought of it one of many highlights of his profession.
And who would not be pleased with serving to obtain one thing that had beforehand been a fantasy for the ages?
