Well Golly!

OK, what is it? Three of these hummers were spotted flying together over Texas and a photographer managed to get a decent close-up of one of them. The aircraft's profile does not fit any known U.S. aircraft, although it is somewhat similar to the X-47B drone aircraft but larger. Perhaps they are drones but a radio transmission was also picked up indicating that they may be manned. If they were supersonic then drones could probably be ruled out as all current generation drones are subsonic. It has 2 engines as documented by the contrail above the one shown. Nice to know somebody is minding the store.
