Many times, I thought I was first to an important revelation in the Alien universe to only find it documented, months old or longer, on https://alientimeline.wordpress.com.
The entire timeline previously shown on WeylandIndustries.com is documented and cross referenced on the above website and it is highly recommended when researching anything (a planet, vessel, character, date and the source) for topics, projects, or entertainment.
The below videos from the producer are great.
USCSS Prometheus
USCSS Covenant
USCSS Nostromo
USCSS Sulaco - Hadley's Hope
USCSS Patna
USM Auriga
Thank you Scott Middlebrook for the time spent producing great Alien research and entertainment products.
