I heard a rumor that all of the detainees release from Gitmo and other US facilities have had a secret tracking device implanted. This allows GPS tracking by secret satellites
This device can not be detected by normal x-ray machine nor does it emit any discernable radiation.
It can however be detected on a few occasions when subjected to x-ray radiation for 14 days. This results in the device being detected about 0.98% of the time. (caution this level of radiation can cause sterility in male elephants at 2.75 miles.)
Don't tell anyone!
Oh Yes, the Highlander and Avalon are both fine!
