Like that morphing multicolored starfish-shaped craft viewed by the airport tower and pursued by the pilots of the Iraqui airforce in 1976? That one? Which you dismissed as ball lightning? lol! Or how about the triangular craft witnessed by thousands over Belgium in 1989? That one? Or perhaps you're referring to the saucer that was witnessed by airport workers, tower personel, and pilots hovering near Chicago O' Hare in 2008 that shot up thru the clouds leaving a hole in them? That one? Or maybe you're referring to the egg-shaped craft that landed in Zimbwe and had a person in a silver suit come out of the hatch that 64 children saw at recess in a nearby field and which then took off? That one? Need I go on?
