036 SCPs

 Once every year, a mobile task force is dispatched from Containment Command-02 in [EXPUNGED] to Site-22A to defend the runway and airport located there. The civilian facility is to be cleared of all non-SCP personnel by 0400 hours of September 23 and none are allowed to return until sunrise the next day. On October 1, all civilians must be evacuated again before sunrise and will not be allowed on to Site-22A until the return of the "Pilgrimage flight."
