On the back of one odd piece of Boeing propaganda for the 2707 SST were a few paintings depicting the wonders that the SST would bring. This one depicts the interior of the SST. It seems, by modern standards, quite empty and spartan… what happened to the overhead baggage stowage? There seems to be only a little of that here.
Also, notice that the stewardesses/flight attendants/whatever seem to be wearing bubble helmets. This is not doubt pure artistic license, meant to make it look more mid-1960s Future Cool. But having flown recently, and having spent those seven or eight hours cooped up right in front of someone who spent the whole trip coughing up their lungs (and, unsurprisingly, I came down with the plague within the next day or two), I know *I* would certainly want to wear an environment suit if I had to spend my days in a sealed aluminum tube with hundreds of random strangers. Hell, next time I fly I’m wearing a gas mask.
