 PO1 Perry fabricated a box of plywood and shipped it to John O. Perry in Compton, CA.It has been very difficult to track down the squadron and pilot who flew the Ki-61 Hein striking the Hinsdale on that fateful morning.It is known that seven Type 3 fighters (Tonys/Hein) of the Hiko 67 Sentai sortied from Ishigakijima toward the seas around Okinawa that morning; but many records have been lost.
