03/15/2006. Remarks by Johan Visschedijk: "This aircraft never took to the air (apart from a hop during high-speed taxiing trials). The problem of vibration in the power transmission was still not solved when the Navy terminated the program. Nicknamed "Flying Pancake" and "Zimmer Skimmer", it was a design of Charles Zimmerman. A wooden test vehicle was flown as the V-173."
