Martin Caidin's 1964 Marooned tells the story of a very tightly constrained soon-to-be then-near future of the 1960s as Major Dick Pruett, pilot of an extra final Mercury mission shoehorned in before the first Gemini flight--which in the real world ended up being in 1964 for uncrewed tests, with live missions starting in 1965--ends up stranded...er, marooned, one might say, in space by failed retrorockets and hence seemingly fated to run out of oxygen before the drag of the upper atmosphere otherwise would bring the capsule down.
The retrorocket "system was foolproof," concludes the third-person narrative after spending a full page describing its location and design. "It had so many redundant features that even the backup systems had their own backup systems. It was foolproof." Of course... Well, nevertheless, "[i]t had failed" (1964 Hodder and Stoughton hardcover, page 17).
"You could handle just about anything in the way of an emergency," the experienced Pruett knows. "Anything--except a failure with the retrorockets" (page 37). And without retrofire, by the time his ship of its own accord finally began to "drop back into the upper fringes of the atmosphere," then even if Pruett had "used every trick in the book and invented a few new ones" to "extend the lifetime of his oxygen supply system," the pilot already would been "dead for barely more than half a day--fourteen hours--when his coffin started its fiery plunge back to earth" (page 25).
"Years of flying, much of it in experimental airplanes where mistakes and sloppiness brought only disaster, [have] created in him an unbending drive toward perfection." Still, Pruett "realize[s] that it [is] possible he could have overlooked something, some small and, at the time, perhaps seemingly unimportant item" (page 40). Thus when Mercury Control asks for him to do "a complete review...of all procedures and steps taken during [the] mission" in the hopes of "recall[ing] anything, no matter what, that might have been out of the ordinary" and thus "might give them a lead on the retro malfunction" (page 27), Pruett knows that he must "approach the problem from an oblique angle,...enter it slowly," so that no "desperate attempt to discover the error, if indeed there had been one, would...fog his thinking" (page 41).
Of course, with this oh-so handy command to, essentially, "let his thought drift idly, washing gently to and fro in the memories he knew and cherished most of all" (page 41)--with the corollary, not specified by NASA, that the "most cherished" memories must be more than simply the "almost forty-eight orbits" (page 30) from launch to planned retrofire, right?--the author sets himself up for the flashbacks that scene by scene, sometimes interspersed with the present predicament, will reveal not only the planning and training for this mission but also the personal history that led the astronaut to this point.
We will ride with the main character, therefore, up and down the timeline of his life, from the tiny capsule that is the pinnacle of American science, back to his teenaged years during the war "thumb[ing] a ride" to bum around Roosevelt Field and "get close to the planes," going for hops in the "clanking, wheezing" old ship with an older pal of his (pages 42-43). We will see the young Pruett later, after the departure of his friend, doing "odd jobs here and there" in exchange for "pay in flight time" (page 46), then graduating from high school in '43, joining up, earning his sterling Army wings, and then taking postwar tutelage under "one of the true 'old timers' of aviation" (page 50), a family friend whose teaching humbles the cocky man and ultimately keeps him alive "at 43,000 feet" in "a lousy, cold place called Korea" (page 66). We will learn the politics and technology and training regimens of the Space Race as well, with emphasis, though not solely so, on the Mercury Program and also the soon-to-be launched Gemini that will help America learn the techniques needed for the Apollo missions to the Moon. And we will meet the dame who, after witnessing a fiery crash that kills a friend "only fifty feet in front of them" (page 189), tries to make him choose between flying and her...
Martin Caidin's Marooned may be a little florid in its language every now and then, and sometimes a little over-adulatory of its protagonist, but overall it is an enjoyable and exciting tale of the early Space Age, a nail-biter that also evokes the love of flying and even something of the process of human maturation, too, and will be right around a 5-star read for anyone interested in space flight or aviation.
And if we read the version updated in 1969 for the film of that year, whose screenplay was by Mayo Simon...well, then we will find the plot updated to an early 1970s post-Apollo situation of a similar accident while returning from a Skylab-type mission, now with three crew members, one of whom is suffering something of a mental breakdown, and we will discover that the action and suspense actually are even stronger than those of the original.
