Re-reading Dan O’Bannon’s original script for Alien. This section reminds me of Fifield and Milburn talking about the dead Engineers and the crew speculating the use of the pyramid in Prometheus.
Broussard: I’d bet my share on it. There’s no doubt in my mind.
Melkonis: Poor Yorick (space jockey) must’ve thought it was pretty important, used his dying breath to scratch it on the panel. (They are talking about a triangle shape etched into the panel in front of the space jockey)
Faust: A warning?
Standard: An alert certainly.
Hunter: To who?
Standard: Whoever came along.
Roby: Whoever’s stupid enough to land.
Broussard: A marker for buried instrumentation?
Standard looks at him, at the pyramid.
Standard: Hell of a big tomb.
Hunter: A tomb or a mass grave.
Broussard: or maybe they’re alive in there. Or hibernating. Or in suspended animation. Waiting for somebody to come along and rescue them.
