Hmm, why is there a oversized skeletal-like bird creature gliding over the trench?
Hmm, I have multiple theories.

Or, it may have been that 'The Plane' is actually a huge threat itself to the player, and it's red eye actually is a memetic effect to make the player 'faint'.Maybe 'The Plane' was originally a bird, but was sent into the PD, later to either corrode and grow into a massive, homicidal eagle.
The new trench is mysterious.
There's a sinkhole that also leads to the exit room, Inorder to escape well, avoid looking at the eye, If you look at the eye, your fucked up.
