 The Ki-92 also had a sealed cabin with double glazed windows seating 34 troops in 4 rows (including two emergency seats) to reduce the need for oxygen, and forced draught cooling in low drag engine nacelles.Due to various repairs and modifications, the first flight did not occur until April 1945.The test flight recorded a maximum speed of 426 km/h, but the Ki-92 was found to be dangerous to fly with the cargo door open at these speeds even though fuselage rigidity was not a problem.
