The U.S. and the U.K. now appear to agree that a bomb brought down Metrojet 9268. Numerous reports quoting unnamed sources say the bomb theory is now front and center. The U.K. banned flights to the Sinai area on Wednesday. There has been no official judgment on the theory by any of the many bodies involved in the investigation but that seems likely soon. It appears signals intelligence played a role in the developing theory, along with satellite imagery. Egypt's ISIS affiliate has claimed all along that it was responsible but that was discounted because it was assumed that a missile must have been involved. Now the evidence seems to point to an inside job at Sharm el-Sheikh Airport where the flight originated.
