Per 
SCP - 3917
object class - Euclid.
Scp - 3917 is currently manifested as a plane ( 737-800), previously branded as "British airways". it consists of thirteen (13) humanoid entities, averaging 1.3 meters tall, showing no extra-normal signs at first look. they are dressed in standard british airways uniform, exempt from "the pilot" who is wearing a blue pullover and red jeans.
Scp 3197 is currently contained at site 19-B in a hangar to the west of the facility. The plane (Scp 3917-A) is to be cleaned by a team of three (3) D- class personnel on a bi-weekly basis.the "cabin crew" (scp 3917-B through to scp-3917-N) are dormant, unless within 1 metre of a human that is sitting in the wrong seat. seat {REDACTED} seems to be the only seat that the cabin crew do not attack sitting humans on. testing with animals that sat on a random seat, the cabin crew found quite aMOOsing.it ended out with a containment breach after 15 minutes of testing,resulting with {REDACTED} scientists dying by severe bloodloss from on average ten (10) wounds, after they had all sat down, starting their shifts.
Addendum
scp-3917 has no longer undergone testing after incident 3917-1B ,as Dr. bernard had "shut the gate" on all biological substances entering SCP-3917.it is now stored in a 100x100 aluminium cube so no testing will ever happen in the future.
