The story on the Oklahoma City TV station's website had an Associated Press byline.
Don't laugh at balsa wood. The gliders used by paratroops in WWII weren't any too substantial, but the Germans learned to take them seriously. Sort of like - box cutters.
Have you ever seen any of Paul MacCready's aircraft?

Dr. Paul B. MacCready and Dr. Peter B. S. Lissaman, both of Pasadena, California, designed the Gossamer Condor, which is made of thin aluminum tubes covered with mylar plastic and braced with stainless steel wires. The leading edges are made of corrugated cardboard and styrene foam.

Corrugated cardboard? Bwahahahaha. Oh, wait; he won the £50,000/$95,000 Kremer Prize with it. Never mind.

The airframe is so intricate, flimsy, and aeroelastic that defining it for a computer analysis would have taken too much time, says Dr. MacCready. And had he been able to model the craft on a computer, he would have had confidence in the calculated results only if they had been verified by testing. So he felt it would be faster to resort to the oldest of engineering procedures, using a make-and-break approach to arrive at a minimum-weight design.
"A quick-and-dirty approach," says Dr. MacCready, "is sometimes the most appropriate and elegant method in the early stages of a pioneering design. If a part broke, we replaced it with a member that was heavier and sturdier. If a part never broke, we made it lighter and, consequently, flimsier." He points out that this is what intense structural optimization requires when calculations do not play a major role in the process. The fact that the craft was always flown low and slow made destructive flight tests safe and feasible.

If I understand correctly, the Iraqis are allowed to own UAV's, as long as those UAV's cannot fly farther than 150 km. There is no limit on wingspan, weight, and so forth.
Just like us, they show you what they want you to see.
