This is not the hell your whale SCP.
Okay, upvoted because there are enough things here I like to counteract the things I'm ehhh on. First, why is the Foundation bothering to spend time and effort extensively training these people and equipping them to make the trip? Is it just kindness, keeping them from dying and possibly breaching security? Second, it's hard for me to believe that the SCP is an irresistable compulsion that you can temporarily talk someone out of. It's like postponable insanity; you have an incurable disease that forces you to carry out a series of behaviors, unless someone offers to teach you scuba diving. Third, the MTF should have been the SCPS Pequod and you know it.
