Also the 17th May 1990 date of the fax connects with the 29th June 1990 date on the CCTV camera of Ejiofor in the Backrooms in the trailer itself. So that seems to be where these events are going to fit in the whole timeline of the series. That sent me down a date rabbit hole:
The first Found Footage video is September 1996; the second 19th August 1995; and the third is undated but the brief radio clip at the opening talks about the Oklahoma City bombing of April 1995.
(
9780415263573 - an ISBN code - and
home_27647 are alluding to things happened upon during Found Footage 2, so date from at least before that point)
In the hazmat suited Async scientists timeline:
Overflow is dating the government involvement all the way back to August 1972!
___
Prototype is 10th May 1982;
___
The Third Test is 2nd July 1988;
First Contact is 17th October 1989; (there is a tie in unlisted video
- once called "Collateral" and now called "faultline.mov" - that implies that this event caused the 1989 Loma Prieta earthquake)
___
Lighting and Tile Survey is 14th/15th November 1989;
Missing Persons is 3rd February 1990 (showing that the spike in missing civilians is beginning around this time);
Autopsy Report is 5th February 1990;
Informational Video is 29th February 1990 ("Never enter The Complex alone. All expeditions are to be comprised of no fewer than three individuals"), which, yes, is a date that never existed. That's the one that first suggested that people are travelling through space in the real world as they go through the Backrooms dimension, as it pays off in Presentation and Reunion.
Mar11_90_ARCHIVE is self explanatory;
Motion Detected is 3rd May 1990, showing footage from 5th and 6th March (and introducing the famous "Big red circle around object of interest" meme! It feels that this specific video also had a significant structural influence on a number of videos in the other great analog horror production, the "Greylock" series);
Pitfalls is 6th May 1990; as is
Report - Pitfalls appears to be the chronological first monster encounter of the series, seemingly with someone who fell into the area, as well as the first representation of an 'outside' area in the Backrooms; and Report is the first short with a full shot on non-glitchy VHS third person filmic approach;
Presentation is 8th May 1990; as is
_recording014. Interestingly in this run of videos we are seeing some of the Executives of the Async corporation wandering about the Backrooms without suits, which potentially may have been an unwise move!
Reunion is 25th May 1990;
Damage Control is 26th May 1990;
Static Dead End is 29th May 1990
___
So, it looks as if the events of the film are taking place long before the other "Found Footage" mid-1990s civilian explorations, and are close to the final videos in the Async scientists part of the series. Which itself is making me wonder whether the origin of the monsters we see in the later Found Footage videos are the main characters here, after having been trapped in the Backrooms for years?
