Well, let me cut short all of your speculations, debates and ideas. The picture you saw was the first prototype of the drone they made. It was simply a RC plane no doubt. But as of today, they have acquired 30 Km aerial suveillance capability with all the way live video. Since the project is very secret, you will not get a picture of it any where. It is indigenously designed and built. I could just look at it while it was being flown during a test flight in Tangail, near the Bangabandhu Bridge just a month back. It makes almost no sound and flew superb!!. I saw the flying and landing, could not see the take off.
