Pilgramige flight

The "Pilgrimage Flight"- A passenger plane provided by SCP personnel for the transport of "the pilgrims," it is manned by a crew of trained Yazidi holy men. The crew are typically never able to elaborate upon details of the pilgrimage or what the kiras guhorîn actually is. SCP equipment on board function optimally but recorded data will only slightly increase our understanding of the pilgrimage each year. Though the flight is gone for seven days, the crew and recorded data are only able to account for a few hours. Days are missing from time recording equipment and cameras, though nothing abnormal is ever observed. The plane disappears from radar and visual contact is lost about 50-60 km away from Site-22A until it returns about sunrise on October 1.
