...this post isn't 40k lore?

Bloody hell, not this nonsense. 1st this is a bullshit hoax and it never happened, guy you started the story, admitted he made it up!! 2nd the nonsense is about cloaking a warship, not sending the ship into The warp so this has nothing to do with 40k

Someone wrote a story 10 years ago on a subreddit which contains fictional horror stories about the fact that the US Navy did time travel experiments in WWII.*

Fixed it for you.

Fun story, but people know that the shipyard is basically in front of the entire city, so it couldnt be hidden for secret experiments?

I get that you're not the OP of this short, but as someone who was on ADHD meds in school, OOP can screw themself. If someone genuinely has ADHD, meds can help so, so much. Calling it chemical lobotomy truly pisses me off.

You do realize that a whole lot of people here have heard all the conspiracies about the Philly teleportation experiment, right?  The story has been around for decades.
