Alex E-S makes a quick return to Friday with an imaginative "no clue" puzzle. Each theme fill is a type of flying machine. Thus, each one becomes an Unidentified Flying Object as they are flying objects not identified in a clue. This approach requires the solver to get the down fill to get at least one of the theme filled. Because of the difficulty of seeing the theme, the puzzle doe have lots of doable, short fill. He did squeeze in OOMPAHS, CARLS JR., BUTT PACK and HER HONOR. The flying machines are diverse, but otherwise I see no other common element.
