Scientists at Los Alamos National Laboratory will be tracking Santa Claus as he makes his rounds on Christmas Eve. Santa will also get help from Holloman Air Force Base in southern New Mexico. As part of "Operation Assist Santa," aircraft from the base will provide a special escort for his journey through New Mexico. Base officials say an F-22 Raptor will serve as Santa's wingman, while the MQ-1 Predator and MQ-9 Reaper will provide "special intelligence" for Santa through naughty and nice sensors and sleep detectors installed on the two aircraft. The Los Alamos trackers will be using state-of-the-art technology to mark the course taken by Santa and his reindeer. They will be helping other trackers at the North American Aerospace Defense Command in Colorado. The following images are a collection of Santa sightings from around the globe during the approach to Christmas.
