Ha ha! I knew I should have forbidden certain forum members from participating in the quiz 
The following is taken from an EXCELLENT AIAA paper by Mike Hirschberg, which i strongly recommend
"To Boldly Go Where No Unmanned Aircraft Has Gone Before: A Half-Century of DARPA’s Contributions to Unmanned Aircraft", which among other things details the early history of the ancestors of Predator (TEAL RAIN, Amber, Gnat, Albatross...).
Anyway, here's some more info:
"Broomstick, was developed in 1986 to explore the limits of airfoil design and straight-wing, high-lift, high aspect ratio aerodynamics. This demonstrator employed 50% thick airfoil sections with circulation control, using differential blowing to provide lift and control while also efficiently achieving a very lightweight, high aspect ratio wing structure."
"The first flight of the electric-powered demonstrator was in 1987, proving the feasibility of extremely thick airfoils and the ability to control a straight (0 degree sweep), all-wing planform. Initially, Broomstick used horizontal and vertical tails for stability mounted on a circular boom, approximately 4 ft long. First flight without the tailboom was in 1992, after standing down for a couple of years waiting for funding to develop the digital autopilot that stabilized the pitch axis. The angle-of- attack sensor was mounted on a “stick” at the rear of the aircraft; this fed into the autopilot. Putting it behind the wing kept the pitch rate from causing dynamic instabilities with a positive feedback loop into the autopilot, creating natural damping. Broomstick flew nominally around 15-20 mph"
