...Several points:
1) George Smith was a sci-fi writer who was friends with Martin Caidin. He also played the Cape WXO in the film as a cameo, as did Caidin, playing the reporter who describes the XRV's arrival at the Cape. Smith died in 1996, IIRC. His short Wikibio can be found here:

2) The SM in the film was in fact built "short", but only to save bucks through the used of forced perspective. Here's an image of how the whole CSM short stack looked from the angle it was *not* supposed to be filmed from:
3) The "Music" style was deliberate. There was a trend going on around 1970 where sci-fi film orchestrators would write scores using unique and totally oddball elements in place of real instruments when they could.
Planet of the Apes' percussion section consisted mostly of steel cooking pots, and the horns section were horns shaped from various animal horns.
Andromeda Strain used a lot of reverb tricks, with the reverbs being backmasked, and some of the same faux telemetry noises mixed in that were discards from the
Marooned soundtrack mixing sessions.
...Much of the reasoning behind the particular methodology used in creating the score was a desire to create a score that would not distract from the tension on the screen, and would only add to the "cosmic wonder" of certain scenes, such as views of the various spacecraft from outside. Like Sandy Courage's "Swwwwoooooooshhhh!" on the Original
Star Trek, the "ship" music served that purpose as much as the sound of the RCS quads - neither of which should have been heard in a vacuum.
Ergo, it was by design, not accident, that the scores for those films -
Marooned in particular - turned out as odd as they did.
4) The payload fairing trick was also used on Countdown, a film that's sorely needed those 18 minutes that were cut before the premier readded, and a whole bunch of special effects shots added so we can see the parts Robert Altman was too cheap to have done - i.e., the shroud sep from Pilgrim, shots of the Pilgrim/Double Centaur insertion & crasher stages, Pilgrim actually landing, etc. There's been some big talk from some of the CGI freaks on YouTube about editing together such a fan edit, but nothing so far in the past six years. Go figger.
5) *ALL* Disaster films following
Airplot (sic) were like that. Audiences ate it up like popcorn until Irwin Allen burned that genre out until the studios teamed up with the anti-nuke freaks and we got the likes of
Meteor, The Day After, Threads, Letters from a Dead Man, and in highly honorable mention,
Testament in the 80's.
6)The $4MUSD take was for the first-run, which was erroneously distributed as a "road show". The re-release in '72 - mostly aimed at drive-ins and big screen theaters - recouped the losses in the first week, and the film made about $12MUSD in the total box office. It got a major boost from rentals when Joel and the Bots got ahold of a syndicated edited version called
Space Travellers and riffed it a new airlock. Took it a while, but the film did make a profit.
7) The one real complaint I've heard from those in the Astronaut Corps is that no matter how bad the situation had become, we'd have never seen one of the crew go berzerk like Buzz Lloyd did. Same argument applies to Jack Swigert's little temper-tantrum on Apollo 13 - it wouldn't happen because everyone is trained to know that no matter how hard you bounce off the walls, you'll still be right where you are. And besides, you'll be using more O2 for nothing.
8) Caiden was asked repeatedly over the years as to why a Vostok - now a decade retired - was used when a Soyuz would have been in full operation by the time the events in the film happened. In fact, the Soyuz would have been able to bring back one of the Ironman crew under emergency conditions, So why wasn't that used?
Answer: "Simple dramatic license". :
