A "mixed grill" formation of a variety of aircraft led by a captured Japanese fighter aircraft Nakajima Ki-84 Hayate (Gale, allied code name "Frank"), of the Technical Air Intelligence Unit SWPA which had been discovered at an abandoned airfield in Luzon, Philippines, after the U.S. recapture of the island in January 1945; the first aircraft of this type was disovered on the island of Leyte. This aircraft was operated by the Technical Air Intelligence Unit, South West Pacific Area (SWPA) located at Clark Field, Luzon (Philippines), from the end of January 1945. Other aircraft in the formation are a Royal Navy Seafire (lower left), a U.S. Navy Grumman F6F-5 Hellcat and a USAAF North American P-51D Mustang. The Nakajima Ki-84 models fitted with engines exceeding 1800 horsepower could surpass the top speeds of the P-47D Thunderbolt and the P-51D Mustang at 6,000 m.
